About a year ago I would have said Cotto with ease.Lately with Margarito's last performance I would say Margarito has the upper hand.He hasn't been down that I could think of,He takes one helluva shot,and does usually throw alot of good hard punches.Cotto to me was hurt against Mosley and down against lesser oppenents.Granted it was because he struggled to make weight,but Corley.In theory Cotto, but a a big welterweight and decent puncher in Margarito who throws a shitload something Cotto has never seen or been up against.Hard to say
