I would like to go for speed.I like watching the guys with fast hands.In terms of what would help me win more fights i would probably go for stamina.Speed is great but it is useless without the stamina to back it up.A fighter with good timing and a cool head will negate speed.Good stamina is a solid foundation for everything else to be built on.
Long story short I would go for Stamina
Cotto has a defense which is too porous.If you look at the punch stats from most of his fights, his opponets often land something like 40-50% of their punches.Floyd will do fine on the inside
Damn! people in this page really think mayweathers a God... Hope Cotto beats him up!
Looking forward to seeing how Floyd is if Cotto manages to catch him with a left hook
