Margarito would beat Williams IMO. Its funny that Margarito's overhyped but Williams has fought 31 fights and out of those the only guy he's faced is a shot Sharmba Mitchell. Maybe you could throw in Matthyssee but he wasn't much. Margarito's opposition pretty much sucks but its just one killer after another compared to Williams'.

Cotto and Collazo would beat Margarito though. Especially Cotto.
