In case that happens and that is an open possibility as any other scenario, Calzaghe can only say that Kessler was in great shape and that he wasn't for some physical reason ( injury, malfunction or disease that may have weaken him down). If he loses by decision and close enough, he will question it and alledge some sort of sabotage to his legacy and career for sure.
The official excuse was that he was not a good enough actor to make a believable show of himself losing to an inferior opponent. Personally I think that he won on purpose, and is full of ****.
what u expect its from Paul Davis, who's now gone running so far from these forums he'll cross an international timezone.
