compare that to the list of everyone else from tuf, i would say it's unimpressive that more did not develop, and some are quite overrated.
TUF was never meant to turn everyone into a star, it was meant as a taped audition to the big show. The fact that as many TUF fighters are still around and very much in the title picture or have it, speaks very highly of the show.
