Floyd could win that one, no doubt about it. However, I could see Pacman just ramming him and with his super stamina and relentless punching create some damage, I remember the first FLoyd-Castillo and Castillo should have won, really. The second fight, Floyd won it but it was not a loopsided decision at all, it was a competitive fight, based on that and seeing how Oscar was close (in my opinion) to a draw, I could see arguments why Manny could make it as well, especially that he has the power bombs and the chaining punches to make it true. Well, it could go in both direction depending of the tempo of the fame, let's only hope we'll see it someday.
