Please, it's not like anyone from TUF goes on to do anything in the UFC anymore. Who has become a legitimate top tier fighter from TUF since Maynard? A few have made it into the top 10, but not much else. And every division is overflowing with fighters already, so I'm not concerned about the few guys that might add.
I think it's time for a Strikeforce TUF.
Cast a ton of guys from different divisions of Strikeforce, and the best get UFC contracts.
