I think the only fighters who could potentially beat Ward right now are Bute or Andre Dirrell (if he's the same after returning from layoff) but even still you would have to favor Ward in both those matchups based on his versatility.

Calzaghe would of beaten Ward in my opinion prime for prime. Ward tired late in the fight against Froch who wasn't really throwing or landing many punches. Calzaghe with his workrate would certainly test Wards conditioning.

I think Ward would be tricky for Joe in the first few rounds but then Calzaghe starts to get his rhythm going then ups the workrate eventually outworking Ward down the stretch.

I don't get the comparsions with Ward and Jones or Floyd,etc.

Andre Ward right now reminds me of an older Hopkins with a slightly higher workrate.

Ward like an older Hopkins picks his punches well and utilizes all his tools whether it be on the inside or outside.
