Khan has a good jab but Cotto's is great, even still at his age. Khan's jab is probably faster than Cotto's is at this point... not better though in my opinion.
khan has a good jab and its speedy. but cotto works so well with his jab.. honestly he is a shining example of what a great jab should be.. he utalises it so well to get inside and do his damage. always loved watching that guy fight
But he beat Hoya and Cotto. So obviously he had some idea of what to do. Cotto actually landed less than 3 jabs a rounds. There were multiple rounds where he didn't even land a jab.
Khan has fast hands, yes, but his jab is nothing special. Don't kid yourselves. Not even close to the level of a Miguel Cotto.
