Floyd's fighting style is the opposite of his pre-match hype persona. Floyd is a quiet fighter. He's very calculating and works more with counter assaults. He'll look like he's always on the defensive but that's just until the opponent gets close enough to attack with just the right punch combo.
Manny will have to figure a way around that. He can be aggressive, very aggressive. That kind of fighting style plays right into Floyd's style.
I also give Floyd the edge, but it'll still be completely awesome to see.
