Baroni used to post here, too, but people are such assholes, it's why we can't have nice things on SD.
Yep - Bas Rutten, Tom Erixon back in the day. Gary Goodridge, too.
Throughout the years, they still show up from time to time - and we chase them off.
As for TS - no, I don't think it would increase popularity much - although, ni a cult sense (Alan Belcher) it has a bit in the past.
99% of a fighter's popularity comes from Zuffa's commercials and Rogan's commentary. If Rogan says Houston Alexander is a killer, Sherdog (which is more critical than the mainstream, believe it or not) will parrot it the next day. Machida Era? Yep, the next day. Sherdog is interesting because then you get the minority who speaks out against the machida Era, Ronda being the greatest athlete of all times, etc. and the muttonchoppers get irate, and then it escalates - hence, 90% of our threads, or more.
Anyways, if I was a fighter, I would probably check on here, get mad/disgusted, then say, "bunch of idiots, anyways" and not come on for a few months.... over and over and over.
