Some have tried this and failed. The only difference is that canelo is THE BIGGEST guy floyd has ever fought. And that give him the leverage to use this "mauling" tactic. But if canelo forgets he can also box and use the jab to get in on floyd, he'll be countered into a KO IMO.

But look at the arm difference guys http://l1.yimg.com/bt/api/res/1.2/hs...ACEOFF-310.jpg

Canelo is a much thicker guy. Floyd could get hurt.
