Yeah. First southpaw heavyweight champ. We also all know him for being on the losing end of the fight with Foreman. That makes him famous, and it's a hall of fame, not a hall of ATGs.
No his only really good win was Holyfield, with that said he's no worse or maybe even better than some that are already in.
No, he wasn't a great fighter and didn't beat enough quality opposition to warrant induction. If they induct a guy like Moorer it will end up being a real slippery slope. They would then have to induct a fighter like Chris Byrd who comparatively accomplished more than Moorer but doesn't deserve to get in either.
No, both not famous enough and doesn't have enough good wins to warrant it. Really he's only well know for losing to Foreman.
