I think they need another HW TUF, they have only had 2 I believe and are have a hard time getting quality Hw's. They should have guys like Pedro Rizzo and other has beens and up and comers at least to fill a decent HW slot.
but I wouldn't mind seein Tim getting 1 more shot, he's a quality gatekeeper and if he has a bad showing cut him....just like everybody else said. I'm sure he wouldn't demand much money.
I think the real reason is that he was an embarrassment when he got starched by Fedor in 30 seconds then lasted 9 seconds with a 50 yr old mercer. It basically made the UFC look bad having a "former champ" getting humiliated so bad.
