If he decided to make the decision to come back then we would have to respect it, afterall he knows his body. If he came back I would say a couple of unknowns with weak chins, then a few more very low level fighters maybe that some would know before fighting some well matched good names.
Yes, at least some money is still to be made. Not sure how much, but you know his name would still generate some decent interest/income for him. A low level opponent streak may make him more money that you think. Tyson is legendary, as we all know. Shannon Miller.............Rob Calloway..............someone like this, then see what happens from there. Even though he was once a big name, forget someone like Bowe, who is punch drunk, fat as hell and flabby..........Tyson's opponent can't be a big fat guy who looks like a bum off the steet (that rules Arreola out.........LOL) . It'll have to be against a mediocre but decent fighter who at least looks like a pro boxer in order to make the fight at least somewhat interesting. But at the same time, he can't be too much of a credible fighter, as he may beat Mike, and blow the whole thing............LOL Look at the McBride fiasco.
I'm convinced that if Tyson was with either Kevin Rooney, Tommy Brooks or Richie Giachetti and trained very hard, he could at least obliterate Kevin McBride & Danny Williams even now. It would be nice to see him get revenge on them two at least.
