if both jc and kessler left then if mundine was ok itd be him but hes blind in his left eye so id say lucien bute or carl froch
If Calzaghe wins and immediately moves to 175, then the no.1 would be Kessler. Unless one of the other fighters beats a fellow top 10 fighter, such as Bute beating Froch.
How can you consider Carl Froch and Lucian Bute in the same class? Bute fought has beaten world class opositon while froch remains untested. Bute is fighting for a world title (againts Berrio but still....) and Froch is fighting an old Robin Reid. Bute is way ahead of Froch right now.
Kessler. Even if Calzaghe does a Lacy on Kessler, Mikkel has still beaten way better fighters than guys like Bute and Froch. Mundine is 3rd for me right now and Kessler already beat him.
Kessler will still be no. 1. At the moment he is considered no. 2, and losing to the no. 1 won't change that fact - not until someone else underneath removes him as well.
