Alright I read the 1st page of this thread and I am probably the biggest Mayweather fan on these boards, I am compelled to say whomever started this thread is no real fan of Boxing
Cotto beat a not prime but Hungry and game Shane Mosely who was in this fight because he was a major player and talent in the division, not a spectacle sideshow freak fest pimping out his once great name. I was already a fan of Cotto, but he really showed more dimensions and facets of his game.

He has extremely deceptive handspeed
tighter defense
developed a dynamite jab
timing
outstanding counterpunching.

Cotto is here to stay and can beat Floyd on any given night. I would still give Floyd all the advantages and predict a Floyd victory but Cotto is a juggernaut
