He could have made alot more money. He still can if he ever steps in the ring. He looks to be in good shape.
Seriously? If he had been in good shape he could have done something earlier in his career. He could, perhaps should, have been a belt holder already if he wasn't DQ'd by Cortez against Ruiz. Anyway, good luck to him. He needs to stay in shape, fight regularly and he might get some more big fights.
I don't want to kill you because you're a big fan. But what makes you think he'll be successful? He couldn't make it while young and somewhat in shape. Now he is old and hasn't fought in four years just about.
I'll believe Johnson has made a comeback when I actually see him in the ring. Being he is going to be 38, always had weight issues, and been off for four years, then I'd expect his doubtful comeback to add up to anything. Johnson put together a decent career but he never lived up to his potential. He had the ability to be a top heavyweight for a while but it never happened.
