Max, I'm struggling to work out your 'rationale'. You think fury is the best heavyweight on the planet, but holmes could possibly have beaten him. But mike tyson couldn't. Yet mike tyson beat the shit out of holmes for four rounds before knocking him clean out! Strange, very strange.
And like darbo above just said, and what I've said all along, fury hasn't really fought anyone of note, apart from a well past his best klitschko, who looked as though he didn't even want to fight. I won't include wilder as a proper oponent either, cos he's ducked every f****r all his career
