This means only one thing: that Floyd think that Manny can actually hit him and hit him hard, and the only way he can counter that is to do just that, trying to out-punch him by being aggressive. To me this could be a sign of desperation on his part. But there is one thing I'm a bit concerned about. It's Floyd's sneaky and quick jab/straight to the body. He does it so well so I hope Pac will be ready for it.
