For an ambassador of the sport, which is trying so hard to legitimize itself into the mainstream, to openly date a porno star, like it or not, is only hurting the image and cause. Tito can beat Ken Shamrock, and struggles with T.U.F. castaways. Get rid of him and his freakishly altered porn wife and move forward. Like it or not, Dana and Zuffa have done great things with the sport.
Tito wasn't exactly a non-factor in the popularity rise of MMA either. I didn't say I had anything against Dana, or Zuffa, but I've read alot of stuff suggesting he's not very well liked in the MMA world. But like I said, he's in the driver's seat so it doesn't much matter at this point.
