I agree, floyd is the favourite in this match up, his style and size advantages make him the favourite to win, pac has been the underdog plenty of times, it usually makes for a fun fight, hopefully with floyd as well.
I feel Pac being the underdog will motivate him in a way he hasn't cared for since Cotto. It's not that he's far past his physical prime or anything, but I want to see him hungry and throwing punches to the last bell even if he's losing like in the first Morales fight. I think he'll care more this time around.
