The way to beat him is to find out if he's fragile. By that I mean rough him up, like Hatton fought Tszyu. Push,shove, run into him with your shoulders, hit his body, his arms, lean on him. When PBF goes to the ropes and in his shell ready to roll or block punches, lean on him and push him into the ropes, hit him in the body while their breaking, etc.

ODH said he was going to make it a rough fight, but that is really not his style. I think he had the gameplan to beat PBF, but it's not his style to fight that way so he didn't execute it well enough.
