everyone falls asleep :: tough call. 130 was Casa's prime, but he's almost the opposite of Guzman. He gave away early rounds, a point in the fight in which Guzman is usually at his best. It'd be Guzman early, Casa late... I guess Casa SD, with everyone bitching about the decision in the end.
Guzman, and pretty clearly, seems to me. Just a bad styles match-up for Casa...Joan does everything Casamayor does better; except maybe his footwork around the ring - and that's debatable. And Guzman would start off leading - and then force Casamayor to lead, which is most definitely not Joel's forte. Guzman can lead better than Casamayor can if forced to. Peace.
