id love to see him on TUF, i think he would stand a good chance, i think if he went on TUF and won then that would stop soeme of the hype of saying that he doesnt deserve to be in the UFC etc etc admitidly he would still get beaten by the UFC fighters but atleast he would proven that he deserves a shot in the UFC
it would bring the more casual MMA fans to watch TUF
it would stop all the hype because he'll be in the same place other fighters of his level and not fighting cans as a circus main event.
It would be the best thing for his career long term. The question is if he's even worried about the long term. He's pretty old he might just want to go cash a few more circus style main event checks and retire a laughing stock.
