Why keep making excuses for Pac? He was supposed to KO Mosley...he was supposed to destroy Marquez. He needed a big KO to prove he's worthy of an equal split with Mayweather. Therefore I see no good reason why he would take his foot off the pedal. Bradley looked hurt because of his two bad feet. And if Pac was too concerned about the headbutt that just proves he can't get the job done mentally. In other words, he couldn't KO Bradley. I don't know why people keep making excuses for Pac. He hasn't scored a KO in 3 yrs. Lately he's been fighting guys who don't actually stand in front of him and that's exactly why he can't get the KO.
