Haven't seen GGG at 168 so we don't know if his power carries (which is something that typically doesn't get asked about in the higher weight classes for some reason).


Calzaghe wasn't big on fighting top tier guys in their primes so I personally think although he certainly is one of the best ever at 168 I think his resume could have been and should have been much better.


Kovalev vs Calzaghe is the question you should be asking
