Its a very tough match to call. I think if the fight is at 140 or 147 and Floyd brings his A game and fights a mistake free bout I'll take Floyd by a comfortable but not landslide UD. If the fight is at 135 and Floyd doesnt train and prepare at 100% I'll take Pacman by late round stoppage or UD. Theres a lot of "What if's" concerning a future match between these 2. Whoever wins will certainly gain alot from it if its a decisive win. If both men are comfortable at the weight the match is made at, they give it their maximum effort and have trained properly it could go either way. I wouldnt want to bet on it thats for sure.
