Why shouldn't Margarito be in there? If it was a P4P list of people who fight like Sugar Ray Robinson then fair enough but it's successful fighters of the moment, however they bloody fight,and after his confirming win over Cintron and eventual Mullering of the next big thing, Margarito's every right to be in there.
Personally I have no problem having Margarito up there, and you are right in that a top 10 shouldn't be based on a boxers technical abilities. I would never try to run Margarito down; he is fantastic at what he does, and boxing would really only be half the sport it is if we only had technical maestros trading jabs with eachother for 12 rounds (boring as **** tbh). We need hard-ass pressure fighters like Margo. I still think he is a bit too high on McGuigan's list, but he definately belongs in any top 10 (at No.5 or No.6 I would say).
