Constant questions about motivation and problems with gassing in recent years
4-5-1 over his last ten fights
BJ was insane when he first broke into the UFC. Holding the title at two weight classes is an amazing accomplishment and fighting at WW at least the second time around might have hurt his legacy.
I would probably consider BJ an all time great but I have to say that his career overall has been a bit of a disappointment based on the true talent he has and how he started off. I have always gotten the feeling that BJ's heart was only in it about half the time and had it been all of the time he could have been so much more.
