Mayweather dominated every second of every round against Canelo.
The speculation began literally seconds after Jimmy Lennon Jr. announced a ludicrous majority-decision verdict for Floyd Mayweather in his Sept. 14 bout with Canelo Alvarez.
It was ludicrous, and not just for the atrocious card turned in by CJ Ross. Her scoring the bout a draw was ridiculous, but Dave Moretti's 116-112 wasn't a hell of a lot better. You can let Craig Metcalfe somewhat off the hook at 117-111, but to most observers at ringside it was hard to find a single round where Mayweather didn't exhibit his dominance.
But that's in the past, and the future is where we must now zoom in our focus. Mayweather was so dominant that he might have done himself more harm than good. There is simply nobody out there—short of a possible move to middleweight—that provides anything close to a compelling opponent and story.
Danny Garcia is the name being mentioned most prominently as the next guy to cash in boxing's lottery ticket. He was certainly impressive in overcoming the odds against Lucas Matthysse, but Floyd Mayweather is on an entirely different plane. There's nothing to indicate he wouldn't get shut out like so many before him.
Amir Khan would've been compelling if he hadn't been beaten three times in fights where he was an overwhelming favorite. His likely opponent in December—IBF Welterweight Champion Devon Alexander—is a good fighter, but he has no drawing power, and there really isn't much else left in the cupboard.
Short of a move to middleweight—or compelling Sergio Martinez or Gennady Golovkin to drop to 154-pounds—it's going to be a tough sell for whomever Floyd chooses as his next opponent.
