mayweather by a landslide. kirkland is a one dimensional pressure fighter with terrible defense. he doesn't handle movement well, and he can't avoid a right hand for the life of him. he should be commended for his heart, but i see floyd landing at will, breaking him down, and possibly stopping him with an accumulation of punishment.
I have said this for awhile Mayweather kills him in the ring. It would be ugly and this is the fight mayweather should take coming out of jail if he was smart
