I suppose Manny is the obviou choice but personally it's Margarito for me. His mesmeric display against Cotto was FOTY for me too.
Manny has wins over JMM, David Diaz and Oscar De La Hoya. Two very quality wins and a title holder in Diaz.
If only Margarito would of had one more fight before the end of the year against CLottey or Williams and won he would of won it for me.
