I think that's unfair. Williams was probably the best domestic heavy for a few years leading into that fight and only got the Vitali shot out of it. Then he went straight back down to domestic class.
I'm a fan but George Groves is definitely living off this 'I beat James DeGale in the amateurs' win. He's still a good prospect but without that it's unlikely he'd be getting this chance at a big box office fight this early.
Ricky Hatton after Kosta? Ricky burns is also a good shout, although his career isn't over yet so can't really judge.
Thinking as well- Young Muttley is kinda living off his win against Jennings. Hasn't beaten anyone else of real quality.
Im going to throw this one out there...... Riddick Bowe I know he beat Holyfield twice BUT that was against a fighter he had great size and stylistic advantages over. Everything else is shoulda woulda coulda
