Hatton is bigger and stronger than Diaz and Diaz was bullying Marquez in the first 2rounds, and he hurt Marquez.I dont think Hatton would have let him of the hook if Hatton hurt him.

Marquez showed what a hell of a fighter is by turning the fight around and ko'ing Diaz.

I think Marquez would use lots of movement from the start if he fights the hitman but in the end he would find Hatton to stong and powerfull and stop him late.
