Golovkin would fight Mayweather

The list of viable challengers for Floyd Mayweather has narrowed, after Mayweather so handily dismantled Canelo Alvarez on Saturday, at times toying with the 23-year-old Mexican en route to winning a majority decision at the MGM Grand in Las Vegas.

Alvarez was younger (by 13 years) and stronger, a natural junior middleweight. But those elements proved immaterial, as Mayweather's hand speed, reflexes, ring smarts and all-around skill set had Alvarez unable to adapt to things he's never seen, and never will again.

The fight was scored a majority decision because an arbiter named CJ Ross scored the scrap 114-114, a draw -- a scorecard which drew immense scorn on social media, including a hashtag of #BanCJRoss on Twitter.

Mayweather certainly looked fit and fast at age 36, with no evidence of slippage. Fight fans looked left, right and center ring, actually, for who could conceivably test Mayweather next. One candidate is Danny Garcia, the 140-pound ace from Philadelphia who came in Saturday as the underdog, as usual, but exited the ring right before Mayweather entered it with a new pile of admirers after the way he boxed Argentine bomber Lucas Matthysse. Garcia was smart, using movement, combo punching and a Teflon chin to get the W.

On Twitter, there was also talk of middleweight ace Gennady Golovkin, the Kazakh mauler who fights on Nov. 2 in New York against Curtis Stevens in a 160-pound tangle. Golovkin has expressed willingness to fight anywhere from 154 to 175 pounds; would he be keen to test himself against Mayweather, who is chipping away at doubters who scoff when he deems himself an all-time great?

"Gennady would fight Floyd at 154 pounds," Golovkin's promoter, K2's Tom Loeffler, told ESPNNewYork.com on Sunday morning. "Whether it's doable is another story."

Mayweather does business with Showtime and Golden Boy, and Golovkin is an HBO fighter -- HBO doesn't buy fights from Golden Boy now, so to get all those entities on the same page would be a task. "Gennady's trainer Abel Sanchez says that Gennady is the only guy who can beat Floyd at 154," said Loeffler. "I don't want to give the wrong impression, I think Floyd has proven over and over that he is the best pound for pound fighter in the world today. But Floyd would clearly be the most compelling fight for Gennady out there. Golovkin is, though, completely focused on Curtis Stevens."
