Jose Luis Castillo is kinda of a poor mans verison of JC Chavez and gave Floyd his 2 toughest and closest fights IMO. I think a prime Chavez could and would defeat Mayweather the pressure from Castillo gave Floyd fits and how many guys where better then Chavez with pressure and a body attack. Floyd wouldnt wanna get down and dirty with a man like Chavez a true warrior.
Floyd did not do anything at Jr. Wltr(or any other div for that matter) to convince me he could handle Chavez.
At 140 Mayweather didn't do **** he's biggest win at that weight was against a shot Gatti!! so i will go with Chavez by UD or late stoppage not to mention Castillo gave Mayweather all hell can handle in both fights Chavez is 10 times better than Castillo.
I see a very similar fight to the Taylor fight just Mayweather quitting in about round 9 or so. Taylor had so much heart and took on everyone. Mayweather does not.
Mayweather close UD. I think he could stay away from his power and get an ugly decision. I can see JCC winning as well.
I'd like to say a Floyd decision but odds are, the judges would favor Chavez like the Whitaker fight.
Didn't Mr Roach say the gloves where loaded a lot ..the way poor taylor was pissing blood. i don't what to believe back then.
