Well I don't know maybe he's just mixing it up with the lesser opponents. When he gets in the ring with pac he'll know what to expect, I mean he got up from 3 knockdowns in the first fight to battle pac to a draw, so I don't see why people think pac would knock him out this time around. Pac might have improved as a fighter, but I don't think his power's become any better, nor do I think marquez has lost any of his heart, no way he'd get koed in 4!
