They are really trying to portray Floyd Mayweather as this bad guy while Shane Mosley is being praised as God's gift to humanity. Mayweather may be cocky, but he as a right to be, he hasn't been tested yet in the sport. That's not because he is handpicking opponents, he has faced everyone except Manny Pacquiao, and has defeated them handily.
Floyd Mayweather is still the most charismatic individual in boxing, maybe even in sports period. Anytime he is on 24/7 it is a must-watch season, and this is really just as good as HBO's documentary show has ever been.
