It's a fact. Everytime Floyd threw it, Pac looked perplexed and was getting hit with all kinds of shots from all sorts of angles. Floyd was too fast, too good defensively!
Seems like he was heavily injured being able to throw with both hands during training, waving to the crowd and during the fight. Pac is just a sore looser and couldn't accept that Floyd outclassed him.
No one outclassed anyone. Watch the fight again and you'll realize both didn't do much at all. It was a very uneventful fight. Floyd did a ton of holding so is this what you mean by outclass?
