I would STILL probably pick Hopkins to do it. Winky has a shot. That's it though, unless you want to start talking about heavyweights.
I think you should have said who out there BESIDES kessler could beat him, because this thread is going to be bombared with people saying kessler and then it'll degenerate to yet another kessler vs JC thread...
The only thing that gives anyone any hope against Joe is Joe's age and maybe, just maybe his reflexes may be slower next time he fights.
The Calzaghe-nuthuggers need to be realistic, he is getting older...his reflexes might be ready to go...he'll be dropping from the top spot of the pound-for-pound ratings very soon.
This is going to sound ludicrous, but I think PBF could beat him. I'd give him a much better chance against the faster, bigger Calzaghe than against a guy like Taylor.
