If the fight happened now I'd favour Alverez all day long, due to him having fought far better opposition. Difficult to say how good Brook is as he hasn't really been tested yet, be interesting to see how he gets on against N'Dou in June.
Whos gives a ****. Alvarez got his hand full with Rhodes. Its a much tougher fight than people are saying. And anyway Brook's a welterweight
Just watched a couple Vids of this Kell Brook kid, not bad... Interested how he does against better competition.
