Well i think pbf has more power than people think. You don't stop 24 professionals without any power. I also believe that you don't see the power because he doesn't fight a power fight he fights a speed fight. He doesn't load up on punches cause hes trying to get it there as fast as possibly. if he sat down on his punches more he would probably have more kos.
As far a baldy goes i don't think power matters. This will be a skill fight. Even though zab lost he was tagging him easy in the first half. Floyd will catch even more and he won't lose focus. Plus i don't think baldy is gonna be able to hit him with anything effective. Gatti was doin a good job of avoiding his punches in the first half. If the defenseless gatti can do that what do you think floyd will do. I think baldy is just too slow.
