Mayweather looks slower and bulkier thesedays, I'd actually like to see him drop down to where he should fight - 140 - and test his mettle there. I'd like to see a Mayweather Vs Pac at 140, or Crawford.
Between 140 and 154 I think there are a LOT more fighters that give Floyd huge problems at this stage of his career. Dunno who beats him but most of the top guys push him harder than he has ever been in the past. You can talk about the "miracle" that Jesus himself performed to make Maidana into a world class fighter but the truth is he hasn't changed much. He is a low end B fighter that pushed Mayweather harder than anyone thought...even if you think Floyd won 10 rounds.
right now, i'd go for SURE Trip G takes him out badly, khan outpoints him and canelo wins in a rematch.. time beats every man, Floyd isn't any different. only those 3 tho, that's how great lol Floyd is, was and will be. we been searching for decades for the true fighter that could take him out and I don't care if Floyd was 28 intead of 38 trip G is the best of the best. age is the reason for khan and canelo taking him now
