People will always be talking that there's ONE more fight that a fighter must take...
If Joe Calzaghe fought and beat Pavlik, then Joe Public would demand he fought the next shiny thing.
Everyone said Lacy was the next best thing at SM and would beat Calzaghe. Then everyone said Kessler was the best SM. Joe beat him. Then everyone said B-Hop was the best LH. Joe stepped up a weight and beat him. Now everyone is saying he should fight a MW!?! No wonder he's laughing it off.
(I do highly respect Pavlik though, greater fighter and great bloke)
Also don't be fooled that Joe can't punch... When he sits down on his punches he can punch but a few broken bones changes your style.
