Khan doesn't have the mental discipline to do what he needs to do to win. At some point in the middle rounds he trys to trade and gets KTFO by a Garcia-esque left hook.
Khan isn't going to trade in this one. He's going in to move and try to use his speed to its full advantage. The problem here will be Alvarez' nonstop pressure. He will eventually tire Khan and catch him with clean shots that Khan won't be able to take. This is a very interesting fight despite how one-sided it looks on paper and reminds me a lot of how the public behaved(and rightfully so) when Pacquiao vs DLH was announced.
Khan loses to canelo, faces brooks next...loses to brook.. great payday for him.. end of boxing story
