Interesting, what do you think sways it for JCC? I think Floyd boxes his head off over 12 rounds, especially at 147.
I agree Floyd outpoints Julio at 147 or above. Chavez never carried the weight above 140 well. But, I think Julio outworks and beats Floyd up a bit at 135 and 140.
Mayweather handily. Better peak, better resume (a lot of stay-busy fights on JCC's record) and although it's irrelevant for all-time comparisons I do believe he wins the matchup based on the Pernell Whitaker fight.
