I have no problems with Forrest going into the HoF. Stephan is going just by association. Other than being on the wrong side of the TUF 1 fight, he hasn't done anything of real note in the UFC. Forrest, like has been stated, was the a winner of the first TUF season and went on to win the LHW title. 3 fights with Tito, beat Rampage and tapped Shogun. I have no problems with it. And Stephan was just in the right place at the right time.
I also want to go on record and say I don't mind that Charles Mask Lewis is in the HoF. TapouT has been huge for the UFC and really made MMA clothing a "lifestyle brand". They were innovators and really helped and helped sponsor a lot of guys. Since they wont put a brand in the HoF, inducting Mask was the right thing to do.
