I wouldnt put Pac. He's a great Offensive fighter who doesnt run but most of his oppoenntes havent ran from him or wilted under his pressure. I dont get that kinda intimidation or fear from him that I do from a Margarito type. I dont get the feeling that Pac is smothering most guys and not letting them breathe.
Even when he's killing guys like Diaz, Clottey, etc.... its not due to pressure. He's just better. Mosley ran but that wasnt because of pressure. It was because he felt Pac's power and didnt want to fight anymore
