Technically, he can't just hang up his gloves. I'm sure when he signed with Al Haymon, it could be 3 to 5 fight contract. So this is just his 2nd fight under Premier Boxing, so he will definitely fight win or lose against Thurman.
Pac's version that fought Cotto will annihilate all current 147 lbs champions no doubt.
True that. But at his age though, it will become harder and harder for him to get back to what he was. Age is a real thing, and even if he trains like hell, the closest he could get is to the form he was just after the Money fight, and that is impressive in itself too. Just to think of it, he will always be a top draw fighter, so Al Haymon will most likely milk him till his contract runs out.
