No. Calz would beat Shappy going away. Much as I hate Calz, it would have taken a great, or at least very good fighter to beat him. Czyz was simply a good/solid fighter. The gap in talent is too big here.
Chez is not in fighting shape Are you saying even a out of shape chez would STILL DOMINATE AND SODOMIZE crapslappy?.
I Cannot see Joe Calzaghe do as well with Holyfield as Chez Bono did. But...at 175, Joe is a hard man to deal with, for any man.
