Margarito's KO of Cotto was by far the biggest upset in terms of its impact on boxing and the status of the welterweight division.

The most suprising defeat for me though was Karmazin being KO'd by someone I'd never heard of.

At least most of the other fights we knew it was possible there could be an upset, in that fight it never even entered my head that it was going to be anything more than a routine mid round KO for Roman.
