Not so sure, Tua was plainly disappointing against a fat Rahman, and can get out boxed. You'd have to fancy him against Williams - but maybe Brewster can outbox him.
BTW, I aint seen Brewster in action, but after Tua last performance I think alot of fellas can beat him.
Well I saw Brewtser against Cliff Etienne and straight away it was clear that despite the impressive record he was not anything like a top 10 heavyweight.
I'd definitely give Williams a chance with Brewster.
