I don't think it'll be easy either, but Brook has exceptional timing and will catch Khan with something flush, and in my opinion I don't think Khan will take it well. Brook is a very strong, very big welter and has good power when he chooses to sit down on a shot. Khan would have to fight a very clever fight the whole way through if he wants to win. Not saying that can't happen but I don't think he has the mental discipline or ring IQ to pull it off, especially against Brook. Brook on the other hand has those attributes in abundance. The only advantage I can see that Khan has over brook is his speed and I don't think that's gonna be enough, especially with Brooks great timing as I said.
i guess this is what makes this fight exciting... the uncertainty or the perceived certainty... depending on how you look at it
