Margarito IS a good fighter, although i dont feel he looked good against williams. Notorious for being a slow starter Margarito really didn get started until well after the 6th round, looked quite pedestrian and still won some rounds.
He's a good fighter, anyone who puts forward an arguement to the contrary obviously has the Williams fight in mind. I would reccomend to truely judge Margarito u shud watch some of his more characteristic performances....
