Friday, 6 p.m. ET -- The weigh-in

• More fighters in the house: Juan Manuel Marquez, Sergio Mora, Andre Berto - and, judging by his girth, there are now in fact two Ricky Hattons.

• Lots of boxing stars in the house for the weigh-in: Marco Antonio Barrera, Joe Calzaghe, Ricky Hatton and of course the legendary Thomas Hearns.

• I'm in the arena with the weigh-in a matter of minutes away. So far, I have to say, the place still hasn't really come to life. There's a good crowd here, sure, but there are some empty seats too. Floyd has his fans; he is a huge draw. But it feels as if his fans aren't as obsessive, adoring and rabid as Manny Pacquiao's or Ricky Hatton's.

We'll see how things evolve tonight and into tomorrow.

-- Kieran Mulvaney

Friday, 5:20 p.m. ET -- The time approaches

A crowd started gathering outside MGM Grand Garden Arena by 10 a.m., several hours before the doors were scheduled to open for the weigh-in. I'll be honest: The place doesn't yet have quite the level of energy I had been anticipating. It doesn't have the same fervor as a typical Manny Pacquiao bout. But I have a feeling it will be a slow burn, and fully expect the excitement to begin cresting tonight. By tomorrow, it should certainly have a really big fight feel. I'll be going into the arena in time for the weigh-in, and by then I'll probably have a better idea of how much the anticipation is building.

-- Kieran Mulvaney

Friday, 5:15 p.m. ET -- The defense, again

Brian McCue writes from our nation's capital to ask:

"Floyd Mayweather has been able to use the high left shoulder-rolling defensive maneuver with great success. I'm curious to see if Shane Mosley can get close and when Mayweather uses the shoulder, then use a left uppercut to open up a looping right hand to the head. Any other thoughts on how to manage that defensive maneuver?"

Brian: You're right. The big question is how to crack that defense. There is a school of thought that because it is geared so much to protecting Mayweather from a right hand to the head, that a southpaw might have the best shot at finally defeating him. That is exactly why Mosley acknowledges that, while it is not the be all and end all, a strong left hand is key.

-- Kieran Mulvaney

Friday, 5 p.m. ET -- The movie theater experience

When Leonard and Hearns clashed in 1981, their fight was broadcast on closed circuit; in that sense, Floyd Mayweather's meeting with Shane Mosley will showcase an element of "Back to the Future," as it will be shown in nearly 500 movie theaters across the country, as well as via pay-per-view.

"Seeing these fights in theaters is like being ringside," says Dan Diamond of NCM Fathom, whose theater network will be broadcasting the fight. "High definition on a 40-foot screen: It feels like you're sitting in Sugar Shane Mosley's corner. It's a lot of fun."

Although NCM Fathom strategically locates which venues will show the bout, Diamond says, "In every market in the country, there are fight fans. There is a whole group of fight fans that doesn't get to come here to Las Vegas to see these kind of fights and for them, this is a great experience."

Diamond says the social experience is a strong driver for those who choose to watch in theaters.

"In this day, when we have personalized consumption of media -- and it's terrific. Never before have fans had so many choices in how to consume their favorite music or sporting events or whatever, but with that, we have become somewhat disconnected. And the easiest and safest place to gather is really local movie theaters. When you look at a 40-foot screen in high definition and the room is full of people going crazy with every punch, it's really a great experience."

-- Kieran Mulvaney

Friday, 4 p.m. ET -- Who's the best?

Tommy Hearns and Ray Leonard were asked how they felt about Floyd Mayweather's frequent proclamations that he is the best fighter of all time.

"I don't have any problem with that," Hearns said. "It's good for him to have that confidence in himself."

"I echo what Tommy says," Leonard added. "Fighters have to believe they're better than anyone. It's a confidence bordering on arrogance. But I would have phrased it a little better."

-- Kieran Mulvaney

Friday, 3:40 p.m. ET -- Who would win?

Floyd Mayweather frequently asserts he is the best of all time. How would he do against either Tommy Hearns or Ray Leonard?

"I think Floyd would have been too small for us," Hearns said. "We were big welterweights."

"Tommy Hearns was a freak of nature," Leonard said. "Nobody could beat him at welterweight. Except me."

-- Kieran Mulvaney

Friday, 3:30 p.m. ET -- Fun with Tommy and Ray

Welterweight ring legends Sugar Ray Leonard and Thomas "Hitman" Hearns spent 20 minutes or so talking with reporters.

The two greats joked back and forth (Leonard at one point responded to Hearns' good-natured taunting by admitting he lost their 1989 rematch, which was ruled a draw) but also shared their thoughts about Saturday's fight.

"I see this fight as rather intriguing," Leonard said. "I think most people are leaning to Mayweather, and so am I. I give him the edge. How do you go against success? But I see Sugar Shane Mosley as someone who could penetrate that defense. I did have a premonition that there would be a knockdown, but I see this as a very competitive fight. I see a chess match."

"I think Mayweather is going to come out and try to dominate the fight," Hearns said. "I think Mayweather's going to do well. But I think Shane's going to test him, see how well he can take a shot. Shane has the ability to punch."

-- Kieran Mulvaney

Friday, 12:20 p.m. ET -- Picking the winner

"I'm rooting for Shane [Mosley]," said former two-time world champion Robert Guerrero. "Having been in camp with Shane, I know what he's capable of; he's just an all-around great guy, I want to see him being successful in the fight. He's always in great shape. It's going to be an interesting fight. I'm just excited to see it. I can't wait."

Welterweight/junior middleweight/middleweight contender Paul Williams also picks Mosley.

"Shane Mosley will stop [Floyd] Mayweather," he said in a press release.

Williams' opponent on May 8, Kermit Cintron, agrees.

"Shane Mosley has all the tools to beat Mayweather. Mayweather is a great fighter, but I believe he is underestimating Mosley, especially because of his age [38)]. Mosley's age does not reflect the great fighter he is."

-- Kieran Mulvaney

Friday, noon ET -- The Ghost comes back

Friday night, just across the street from the MGM Grand, former featherweight and junior lightweight title holder Robert "The Ghost" Guerrero fights in a lightweight bout against Roberto Arrieta.

Guerrero is making a comeback after having to step away from boxing, for the second time in the last few years, to tend to his wife Casey, who is battling leukemia. She is now rapidly improving, enabling him to resume his career with, as he told me on Tuesday, a fresh perspective.

"It's a blessing to be able to do what I love," he said. "The whole experience I had with my wife, it makes you appreciate everything so much more. Her fight is not by choice, and mine is. I enjoy doing what I do, and being able to do it, you appreciate it that much more.

"Every time I get in that gym, I do it with joy, because I can."

-- Kieran Mulvaney

Friday, 11:40 a.m. ET -- Floyd's undefeated and favored? So what?

Asked if he was surprised that Floyd Mayweather is heavily favored to defeat Shane Mosley, Mosley's trainer Naazim Richardson said no.

It reminded him, he said, of when another of his fighters, Bernard Hopkins, beat Felix Trinidad in 2001.

"It's not new for me, man. I had an old guy [Bernard Hopkins] who fought a young guy from Puerto Rico [Felix Trinidad] who was knocking everybody out and had 40 bouts under his belt.

"Roger [Mayweather] says all the best fighters are from the Midwest; his nephew's the best because he's undefeated and everyone else has losses. Well, who's the best fighter of all time? Sugar Ray Robinson. Guess what he had? Losses. And guess when he got his first one? When he was 40-0. For me, once I seen [Muhammad] Ali lose and Ray Robinson lose, I knew everyone can lose."

-- Kieran Mulvaney

Friday, 11:20 a.m. ET -- Naazim wanted Mike Jones

Shane Mosley had been scheduled to fight Andre Berto on Jan. 30 until Berto, a Haitian-American, pulled out following the Haiti earthquake. I asked Mosley trainer Naazim Richardson if it had been hard to adjust training in light of that fight's cancellation and the scheduling of this Saturday's clash with Floyd Mayweather.

"The reason why it was difficult, I'll be honest with you, is because of Shane Mosley. We sent Shane on vacation, and he sent this picture back from vacation, and I said, 'Who's that big guy next to you? You got a bodyguard down there with you?' And he says, 'No, I've been sparring with him.' And I said, 'What? You supposed to be on vacation, man.'"

"I would rather for him to have fought on [Jan.] 30. I thought we could have brought somebody in, a young kid from Philadelphia I thought would have been good, a young kid named Mike Jones -- I thought we could have slid him right in. I thought we should have got something in."

-- Kieran Mulvaney

Friday, 10:20 a.m. ET -- Naazim's challenge to Sugar Shane

"Shane [Mosley] wants to be the best, Naazim Richardson told us.

"I told Shane, these other fights are nothing. You got one goal in life now. Go out there and solidify your place as the third Sugar. There was [Ray] Robinson, there was [Ray] Leonard and now there's you."

-- Kieran Mulvaney

Friday, 10:15 a.m. ET -- Brother Naazim speaks

Shane Mosley's trainer, Naazim Richardson, sat down with reporters for a half-hour Thursday and shared his thoughts on how Saturday's fight might evolve, beginning with the frequently stated observation that the way to beat Floyd Mayweather is to watch what Jose Luis Castillo did when losing two close decisions to Mayweather in 2002.

"People constantly refer back to the Castillo fight," Richardson said. "What they don't understand is, Floyd has seen the Castillo fight too. In the fights he's had since, he's answered those questions about guys moving forward.

"Oscar [De La Hoya] tried to stalk him. Carlos Baldomir tried to push him back. Ricky Hatton tried to run at him. He's answered all those questions. He understands the format. So maybe that's not the format.

"People say, "You've got to do what Castillo did." How'd that work out for Castillo? He had some success; was it enough success? And [Mayweather] is not the same kid years ago that [he] is today. This kid has developed. His confidence is much higher.

"This is going to be a fight of us making adjustments. The opportunities are going to be few and far between. We'll have to take advantage of them immediately, because the window is going to close. Nobody's going to be able to do what they want to do all fight long.

"The adjustments are going to come and you're going to have to find another game plan of attack."

-- Kieran Mulvaney

Friday, 10 a.m. ET -- The buzz builds

It's Friday already?

The week has flown by. When I arrived in Las Vegas on Monday, the MGM Grand was quiet and there was little evidence of what was to come.

By Thursday night, however, the buzz was noticeably building. People are arriving, the hotel is filling, the casino is humming and Bert Sugar's drinking is repeatedly interrupted by people who want to take a photograph with my esteemed colleague.

By the time of the weigh-in, I'm expecting the atmosphere to be off the hook.

-- Kieran Mulvaney

Thursday, 3:05 p.m. ET -- Money May

Wednesday's news conference interchange between Floyd Mayweather and the press corps was a lot more agreeable than the one on Tuesday. It was less confrontational, and Floyd was in a much better mood.

At one point, he started looking forward to laying down some wagers on the NBA playoffs:

"I bet on basketball every day. Went 3-for-3 yesterday. Won about $15,000 yesterday. But I lost $6,000 in my house somewhere. The other day, I was looking for something, I think I was looking for my wallet, and I thought, 'It's probably in one of these jackets.' So I look in my jacket, and I'm like, 'Oh, this is just what I'm looking for.' I found $12,000 in there. I said, 'This is exactly what I need.'"

-- Kieran Mulvaney

Thursday, 3 p.m. ET -- Advice for Shane

Robbi Paterson writes from Scotland with this observation on the fight:

"Shane Mosley must not constantly storm forward and pressure Floyd Mayweather for the full course of the fight. I think he makes it an easy fight for Floyd if he becomes somewhat one dimensional with an all-out aggressive approach.

"Mosley must use his jab regularly. I would like to see Mosley really shoot that jab out like a whip like he did during the first Oscar De La Hoya fight. Mayweather's jab is a blinder but doesn't have much behind it. It's a good point-scoring jab that lacks substance. I fancy Mosley to win if he can penetrate Mayweather's defense early and be busy during every round."

Robbi, I completely agree. To me, Shane's left hand is the key to this fight. If he can throw out a stiff jab, hook off that jab and throw it repeatedly, he can win. If he just flicks it out there and loads up on the right hand, Floyd slides to his right (Shane's left) and lands counter rights over the left hand all night.

-- Kieran Mulvaney

Thursday, 2 p.m. ET -- Defense

Floyd Mayweather makes no apologies for rarely -- if ever -- being in knockdown, drag-out brawls. The key to his success, he points out, is his almost-impenetrable defense.

"You can't break through the defense," he said. "I don't care what you do. It's something that my dad learned from his trainers; it's something that comes from the Midwest, from Detroit. It's not my fault that when I fight fighters, that I dominate them. If they can't break through my defense, that's not my fault. It's not cool to take punishment. If I had been in a bunch of wars, then I probably wouldn't be here giving you guys an interview right now."

-- Kieran Mulvaney

Thursday, 1:50 p.m. ET -- Saul Alvarez

Julio Rodriguez writes to ask:

"I know everyone is busy with the main event, but I for one am interested in seeing Saul Alvarez. I have heard so much about him, but I have never seen him fight live. Is there anything you can tell me about him? Is it all just hype, or is he the real deal?"

Julio, I also am interested in seeing the young Mexican. I first heard about him last year, when several fight folks started telling me about a red-haired slugger from south of the border. Alvarez is still very young, of course (only 19), and I'm not sure whether we will learn too much from his outing on Saturday against Jose Miguel Cotto, but everything I have heard about this kid suggests that he is definitely someone to keep a close eye on.

-- Kieran Mulvaney

Thursday, 12:45 p.m. ET -- Fight museum

As is now usually the case with big fights, Tecate is a major sponsor of Saturday's bout, and after Wednesday's news conference, the Tecate team invited media to the launch of the "Tecate Museo de Boxeo," a mobile museum featuring memorabilia from the likes of Oscar De La Hoya, Julio Cesar Chavez, Floyd Mayweather and Manny Pacquiao.

Fight legend Thomas Hearns was on hand for the official ribbon-cutting, and he, Sergio Mora, Fernando Vargas and Juan Manuel Marquez will be on hand to greet fans who want to check out the museum before Friday night's "Solo Boxeo Tecate" card, headlined by Robert Guerrero, which will be across the street at the Tropicana Hotel and Casino on the Las Vegas Strip.

-- Kieran Mulvaney

Thursday, 12:30 p.m. ET -- More Fun with Bert and Kieran

It's becoming a pay-per-view tradition: yours truly and Bert Sugar breaking down the fight on HBO's "The Sweet Science with Bert Sugar." Check out the poolside prognostications here.

-- Kieran Mulvaney

Thursday, 11:30 a.m. ET -- Who's the champ?

My man Dexter Stephen asks:

"Does the winner of this fight deserve recognition as the lineal champ of the division?

Floyd Mayweather retired with the crown and many say Shane Mosley is the best 147 pound fighter in the world. Should this fight start a new lineage?"

It's a good question, and a valid one. Personally, though, I say make the winner fight Manny Pacquiao for that distinction. As long as Pacquiao and Mayweather find ways to avoid fighting each other, then neither of them deserves to be called welterweight champ.

Should Mosley win, and should Mayweather elect to forgo the immediate rematch, I suspect we will be able to have a Mosley-Pacquiao fight for all the marbles. I have no idea what will happen if Floyd wins.

I will say, though, that if Mayweather beats Mosley convincingly, I may be tempted to put him back on the top of the pound-for-pound list, although given Pacquiao's recent dominant run, it would have to be an impressive victory indeed.

-- Kieran Mulvaney

Thursday, 11:15 a.m. ET -- E-mail

Regular correspondent Chris Leonard writes to me with his opinions on Saturday's Floyd Mayweather-Shane Mosley fight:

"Mosley has never fared well against boxers, including Vernon Forrest, Winky Wright, Oscar De La Hoya, Fernando Vargas and Miguel Cotto. Some of these listed weren't great 'boxers' but either gave Shane loads of trouble or actually beat him. He shows to be visibly frustrated when hit clean by jabs in particular, especially against Wright and showed his frustration against Ricardo Mayorga even.

"Floyd, of course, has a great jab, with great movement. I believe the way to beat Floyd is having a great jab, which Mosley does not; he paws with the jab instead.

"Shane's best punches are an overhand right and a left hook. If he is able to time the overhand right over Floyd's shoulder roll defense, or over his shoulder while Floyd jabs to the body, Floyd would be in significant trouble. However, at the end of the day, I think Floyd's ring generalship and overall movement coupled with unmatched stamina will be enough to carry him to a close and maybe even disputed victory somewhere in the 116-112 or 115-113 range."

-- Kieran Mulvaney

Thursday, 10:55 a.m. ET -- The game plan

So what's the plan, Shane?

"When the fight starts, I'm going to go out there, I'm going to throw some traps here and there, touch him here and there, see what's going on," Mosley said after Wednesday's news conference. "I'll probably be able to tell from Bell 1 what kind of fight it's going to be. I'm definitely ready for any- and everything, but you really don't know until you're in there with a fighter."

The consensus is that Mosley's left hand is key, that he needs to throw a stiff left jab as Oscar De La Hoya did during the first half of his split-decision loss to Floyd Mayweather in May 2007, that the jab is the secret to unlocking Mayweather's defense.

"It's been proven," Mosley agreed. "Not just Oscar, but other fighters. [Jose Luis] Castillo fought him good, and some of the southpaws fought him pretty good with their left hands. So maybe it's not a jab, maybe it's just a left hand. But that's just one strategy. I can't just base my fight on throwing a jab. You have to be ready for a bunch of different things, because you're fighting a special fighter."

-- Kieran Mulvaney

Thursday, 10:40 a.m. ET -- A shocking knockout?

Shane Mosley has predicted he will knock out Floyd Mayweather Jr. (Hey, everyone has to have a dream, right?) But while talking to a few members of the media after Wednesday's news conference, Mosley admitted that should he find himself looking down on a prone Money May, he'll be pretty shocked.

"I go for a knockout, but I'll be shocked to see him just laying there on his back like that," he said. "Happy, but shocked. But I'll also be concerned as well, because the times I have knocked out people, a lot of the fighters don't come back the same. Even the ones I haven't knocked out, like [Miguel] Cotto. Cotto had to be rushed to the hospital for his ribs. He wasn't the same fighter after that.

"Fighting me can be hazardous."

-- Kieran Mulvaney

Thursday, 10:30 a.m. ET -- Fun with Mayweathers and Mosleys

Wednesday's news conference was enjoyable, good-natured and respectful. There was some trash talk, sure, but Floyd Mayweather Sr. delivered his with a smile. There also was a lot of banter between the Mayweather brothers at the podium as well as between Jack Mosley and Shane Mosley cutman Cassius Greene, who were sitting in the front row in front of them.

"He's smart; he's slicker; he's clever," Big Floyd said of Little Floyd.

Then he nodded toward Mosley.

"He ain't got no defense," Mayweather Sr. said. "Bad news. You know what time it is. This fight should have happened four or five times already. He didn't want no part of Floyd Joy. He's scared. Look at him! He's scared now. He's scared of me."

Mosley, it should be noted, was beaming at his opponent's father the whole time.

The fact is, the Mosleys and Mayweathers know one another well, as do their teams, and there is mutual respect. So much so that even Roger Mayweather, Mayweather Jr.'s uncle, was low-key and good-humored.

"If this wasn't a great fight," he began, looking out at the assembled group of lunching media, "these people wouldn't be here eating for free." He predicted the fight would be one of the great fights in boxing history. And then he looked out at his opposite numbers in the crowd.

"But when all is said and done, you all can still invite me to dinner," he said. "We all still gonna be friends."

-- Kieran Mulvaney

Wednesday, 4:30 p.m. ET -- We're under way

Floyd Mayweather: "I'm going to go out, be Floyd Mayweather and do what I do best: fight fast, fight smart and fight hard."

Shane Mosley: "It's been a long time since I've been in such a big fight. It's going to be a great fight. I'm excited and happy to be able to show my skills and put it all on the line. It's going to be spectacular. I hope Mayweather is ready for this. It's going to be a great fight."

Richard Schaefer, CEO of Golden Boy Promotions, just made an extremely bold prediction about pay-per-view buys. "My goal is not to break 3 million homes; it is to break 4 million homes."

We'll see. I won't laying money on that one. I'm still predicting 1½ million, give or take.

• Mosley and his team were sitting quietly at the dais for five or 10 minutes before Mayweather and his team joined them.

• Mayweather is roughly -400 at the MGM sportsbook, and Mosley is +300. That makes Mayweather a 4-1 favorite. Or as my buddy Bert Sugar puts it, "Shane is arrivederci: a good buy."

-- Kieran Mulvaney

Wednesday, 3:30 p.m. ET -- News conference

The news conference is about to begin. Everyone is here -- Floyd Mayweather adviser Al Haymon; Shane Mosley's father, Jack Mosley; Golden Boy CEO Richard Schaefer; and Floyd Mayweather Sr. Lunch is being consumed. The HBO crew is working the room, filming writers' predictions. Pretty soon, the newser itself will kick off, and I'll send snapshot quotes as it happens.

-- Kieran Mulvaney

Wednesday, 12:30 p.m. ET -- The best ever

How does Floyd Mayweather stack up, in terms of ability and achievement, against his predecessors and peers? The man himself has no doubt.

"I'm the best," he told us matter-of-factly.

"The ultimate goal in boxing right now is to find a fighter who can beat Floyd Mayweather. And it's not going to happen.

"I'm the best. I don't care what fighter you're going to get, what fighter you're going to name, I'm the best. Throw a name at me, and I'll break his stat down."

For some reason, we just sat there, looking at him.

"Throw a name at me," he repeated. "Throw a name at me. I'm waiting. Whatever they done, I done it quicker, with no [losses]."

Still, none of us threw a name out there, so Mayweather made it clear whom he wanted to compare himself to.

"Leon Spinks, seven wins, beat you? OK," he said.

Muhammad Ali, who lost to Spinks, may have dubbed himself "The Greatest." But at least as far as Mayweather is concerned, Ali doesn't compare to "The Best."

-- Kieran Mulvaney

Wednesday, 12:20 p.m. ET -- Getting his due

If any of you ever find yourselves in a position to interview Floyd Mayweather Jr., be advised that there is a right way to do it and a wrong way to do it.

The right way, if you want the interview to be productive and friendly, is to start off gently, and if you have some tough questions, to throw them in almost casually after Mayweather, whose default mode is to assume the world is out to demonize him, is feeling comfortable.

Unfortunately, when the five-time world champion sat down with a small group of journalists on Tuesday, some of those present either forgot to read the memo or weren't concerned with what it said.

As the critical questions spilled out, Mayweather almost visibly retreated into his shell before wondering aloud whether he would ever receive the compliments he feels he deserves for what has undoubtedly been a career of considerable accomplishment.

"They say I was too big for Marquez, but they say I'm not too big for [Manny] Pacquiao, and [Juan Manuel] Marquez and Pacquiao are the same size," he began. "They say Marquez was too old, but Shane Mosley is older than Marquez. No matter what happens, I'm always in a no-win situation. I get in the sport, I prove myself over and over again. All I did was constantly beat whoever they put in front of me. I'm never going to get my just due.

"They say Pacquiao got fighter of the decade, right? How'd he get fighter of the decade and he got outboxed by Erik Morales and had a knock-down, drag-out fight with Juan Manuel Marquez? I just don't get it.

"All these fighters they put in front of me, they've all been cakewalks for me.

"When I beat [Mosley], all they're gonna say is he's old. That's all they're going to say."

-- Kieran Mulvaney

Wednesday, noon ET -- The drug testing thing. Again.

Inevitably, while Floyd Mayweather sat with journalists on Tuesday afternoon, conversation turned to drug testing -- the proximate cause of the collapse of Mayweather's putative bout with Manny Pacquiao, and one of the unique features of his contest with Shane Mosley.

"I'm loving it," he said of the process that forces him to give blood and urine tests, although he said he did not know how many times he had been tested.

Why was he enjoying it so much?

"Because I know I'm a clean athlete. I didn't start taking vitamins until I was 30, so I know I'm a clean athlete. You see so many different fighters going into comas and dying. All fighters are taking is a urine test. From what I hear, enhancement drugs are making these fighters punch harder and all it is doing is hurting our sport. I want to be able to separate the average from the good and the great. I want to separate the ordinary from the extraordinary. You're an ordinary fighter your whole life and then suddenly you're extraordinary? Come on."

Asked why this quest came to life only in advance of a possible Pacquiao fight, Mayweather and adviser Leonard Ellerbe protested.

"You don't know that," said Ellerbe. "You don't know what kind of internal discussions we've had, and we just didn't make them public."

Then why did they go public on the issue during the Pacquiao negotiations?

"Because the time was right."

-- Kieran Mulvaney

Wednesday, 9:25 a.m. ET -- How much are you predicting?

Saturday's welterweight clash between Floyd Mayweather and Shane Mosley looks set to be the biggest-performing pay-per-view in quite some time, perhaps since Mayweather's record-breaking contest with Oscar De La Hoya in 2007.

For the record, my prediction is 1.5 million buys, which would be the second-most buys for a non-heavyweight PPV. Speaking with reporters in the VIP Lounge at the MGM Grand after his grand arrival at the hotel on Tuesday, Mayweather himself was less willing to commit to specifics:

"Only thing we can do is hope for the best," he said. "Whenever Mayweather promotions and Golden Boy Promotions do business together, it's a blockbuster. There is no limit to what we can do. The sky is not even the limit. If they say a fight is going to do 700,000 homes, it will do something like 1.4 million. The ultimate goal is always to break records."

-- Kieran Mulvaney

Tuesday, 8 a.m. ET -- The week ahead

It's something of a Las Vegas fight week tradition for the two principals to make grand entrances at the host hotel. There is an element of theater to it all, of course: When Manny Pacquiao, for example, makes his Las Vegas "arrivals" at the MGM Grand, it's after he's crossed the street from the Mandalay Bay, where he prefers to stay. And Floyd Mayweather, of course, lives in Las Vegas; after greeting the fans, he slips below to the arena to talk with the assembled media, then heads home. But it provides a great opportunity for fans to see the fighters up close and is really the moment when fight week kicks off in earnest.

I doubt I will ever experience a fighter arrival quite like the time thousands of singing British fans greeted Ricky Hatton before his bout with Mayweather in December 2007, but they are almost always lively affairs. For those of you in Las Vegas or its environs, Shane Mosley will make his grand entrance at 2 p.m. Pacific Time, with Mayweather following a half hour later.

-- Kieran Mulvaney

Monday, 7:15 p.m. ET -- Bright Lights City

It's fight week, people! The long road that, six months ago, began with Floyd Mayweather planning to fight Manny Pacquiao and Shane Mosley preparing to take on Andre Berto has nearly reached its climactic conclusion. Mayweather and Mosley clash at the MGM Grand in Las Vegas on Saturday, and, beginning Wednesday, we'll be bringing you all the latest right here from the City of Entertainment. I flew in from the East Coast this morning -- and boy are my arms tired (thank you, thank you, I'll be here all week). Personally, I always prefer to arrive a little early whenever possible; take a day to unwind, unpack and shake off any jet lag and be ready for action the next day. It's relatively quiet at the MGM so far, with little sign of the big weekend ahead, but that'll change soon enough.

Send your e-mails to with thoughts, observations, etc., throughout the week.
