As Michael Buffer would say: Joeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee Calzageeeeeeeeeeeee! Undefeated multi-divison champ replaces the undefeated multi-division champ. Simple as that.
I'll say Calzaghe for now. I think eventually he will fight Pavlik. Pac is the obvious #2. And he's pretty close. One slip from Calzaghe could see Pac take #1. It's a very close comparison.
vacant... floyd's still fighting..it should still be floyd. i don't see a 147 version of either pac and calzaghe beating floyd h2h
