Five Rounds: Tito Ortiz talks Rousey-Justino, flyweights and more

Each week, ESPN.com writer and MMA Live Extra analyst Brett Okamoto provides his take on the hottest topics in the world of mixed martial arts.

This week, Okamoto squares off with MMA legend Tito Ortiz to debate the latest news and trends. Ortiz, 40, a former UFC champion, is 2-0 under the Bellator MMA banner and will challenge for Liam McGeary's light heavyweight title on Sept. 19 at Bellator 142 in San Jose.

1. Will a superfight between Ronda Rousey and Cris "Cyborg" Justino take place in 2016?

TIto Ortiz: I hope so. I think the fans deserve it. Cris wants it, but I don't think Ronda wants it. It's in her corner. If she wants to make the fight happen, it's up to her to make it happen.

Brett Okamoto: Yes, it's going to happen. I disagree with Ortiz, though. It's up to Justino to make it happen. For now. Justino has to make that serious effort to drop weight and get to 135 pounds. She's finally committed to making a run at it, so let's see how it goes. I waver back and forth on whether or not I think she can do it -- but her team is confident. It's taking longer than I originally thought it would to come together, but I do believe that come July 7, 2016 (UFC 200), we will see that fight.

2. Who is the favorite to win Bellator's one-night, light heavyweight tournament: Muhammed Lawal, Phil Davis, Emanuel Newton or Linton Vassell?

Ortiz: Emanuel Newton. I like Emanuel, I think he deserves it. But it's a tough four-man tournament. Whoever finishes the first fight the quickest will probably be the one who wins it. Fighting twice in one night, it's challenging.

Okamoto: Phil Davis -- by a pretty wide margin, if you ask me. Like Ortiz, I like Newton and I think he's underrated, but he fights Davis in the semifinals and I think he'll struggle with the wrestling. The other semifinal, between Lawal and Vassell, is a closer fight in my opinion. Whoever wins that fight, I'll predict he has to work harder for it than Davis will have to work for his. Lawal, specifically, just doesn't strike me as a guy who will benefit from fighting twice in one night. He's the oldest in the field. Vassell is an interesting dark horse. I wouldn't sleep on his chances.

3. If you could create a fantasy four-man, one-night MMA tournament using any fighters in their respective primes, who would be in it?

Ortiz: Any weight? Myself, [former Pride middleweight] Kazushi Sakaruba, [former Pride middleweight champion] Wanderlei Silva and [former UFC light heavyweight champion] Vitor Belfort.

Okamoto: Let's not mess around with this one. Straight forward, GOAT tournament: Anderson Silva, Georges St-Pierre, Jon Jones, Fedor Emelianenko. I know there's a major size discrepancy in there, but we're just going to have to work with that. Silva-GSP would be on one side of the bracket, and Jones-Emelianenko on the other. If somehow we get a welterweight GSP versus heavyweight Emelianenko in the finals, I guess that's why it's a fantasy tourney, right?

4. Is UFC flyweight champion Demetrious Johnson the No. 1 pound-for-pound fighter in the world?

Ortiz: Demetrious Johnson is the No. 1 pound-for-pound fighter, yeah. The guy doesn't get touched. He's so fast and slick, his combinations and takedowns are so fast. The guy is "Mighty Mouse," for sure.

Okamoto: Yes. Everyone seemingly has his/her own way of measuring the "best fighter in the world," but I think Johnson has reached a point where he has to be considered No. 1, regardless of how you decide it. He completely dominates his weight class -- more so than any other male champion, I would argue. He's more active than the other two fighters you might consider: Jon Jones and Jose Aldo. He's a finisher. He doesn't have any holes. His game would absolutely translate well across all weight classes. I don't think there's much of a debate, honestly. As great as Jones and Aldo is, the title of best fighter in the world belongs to Johnson.

5. Is Johnson -- and the flyweight division in general -- exciting to watch?

Ortiz: I think the flyweights are extremely exciting to watch. Demetrious Johnson is exciting to me because I like watching an artist draw a beautiful painting. The way the guy strikes, wrestles, his counterpunching -- the average fan watching MMA might think it's slower than some of the other weight classes, but I'm a huge fan of "DJ."

Okamoto: It truly depends on who you ask. To a casual fan, the fan who watches a handful of events per year, is the flyweight division exciting? No, it's probably not. Because it's technical. A lot of what Johnson does that makes him so special and unique just isn't designed for the highlight reel. If you don't know exactly what you're watching, I can see how it would be easy to not appreciate Demetrious Johnson. In other words, if I were introducing MMA to a group of new fans, I wouldn't play a Johnson fight to get them hooked. To those of us watching the sport on a weekly (or daily) basis? Yeah, Johnson is very exciting. He's basically chasing perfection.
