One name i haven't seen mentionned in these forums is Winky Wright. Although i seriously doubt he would fight him, it would be interesting and if Winky still has the stuff(we will know in his next fight as a tune-up, then another fight against someone like Glen Johnson...), i think Joe vs Winky could be interesting. Chad Dawson obviously comes to mind also, if Chad gets another abc belt or beats a good opponent(bernard, Winky, Glen Johnson rematch). Anyone else im forgetting. Kelly is out of the picture, Abraham is 2 weight class below(too much).
I am not interested in seeing Winky-Calzaghe. If Calzaghe is going to fight anyone, I think it has to be against Hopkins or Dawson. MAYBE someone like Clinton Woods, but that's an obviously inferior option.
