I think Casamayor takes this one late, for all the defensive wizardry Guzman is known for he has no offense to keep Casa honest. If Funeka was able to walk through Guzman's jabs and left hooks, there is no reason to think Casa can't do the same. The next obvious thing is to point out Casa doesn't have the volume of Funeka, to that I say he has something much more important pinpoint accuracy with a short left hand.

Guzman is going to look like a phenom for about 3 rounds.

Casa will start landing some meaningful shots in the mid-rounds

Casa will stop Guzman in the championship rounds.
