He doesn't want to risk his 0 which is fair enough this late on in his career. Why take $65m to fight Manny when he can make $20-30m fighting someone like Victor Ortiz? Less money but still a HELL OF a lot of money with less risk. If he loses that 0 he loses all marketability. For the record I think he'd beat Manny but if he doesn't want to take the risk, that's up to him.
