I have a theory on the fight, and I haven't heard anyone else say it. Manny can work the angles when he fights, can throw punches when he is moving and from off to the side like few others can. He's got power and also finesse. Floyd is a master at avoiding getting hit by using his shoulders to block and rolling off to the side to get out of range. I don't think that he can do that with Manny with the success that it has had against other fighters. Especially if Manny slows him down, Floyd will be very vulnerable to the speed and power against him. Not an easy task, but I think Manny could get to Floyd enough through the rounds to get the win.
It could be a great fight, both guys in super condition, one man's strengths on offence against another's on defense. I don't think it will be a repeat of what happened against Marquez, when Manny walked into the punch. He learned from that. He's not afraid to mix it up though, so anything can happen. I know the smart money is pretty much on Floyd, but I think Manny still has greatness.. He trains very hard, has an excellent corner, and nobody can say that he isn't a smart and very aggressive fighter. Floyd is smart too, and highly gifted. The question is who brings more to the table. I hope it goes into later rounds and both fighters can really show what they still have at their ages.
