How about that Chuck Liddell losing to Rampage Jackson last night? Hate to see that happen. Chuck has become the face of the sport, and then he goes out and loses in less than two minutes to a decent, though not great, fighter.
I predict this kind of fight could be what holds MMA from becoming a truly great sport. People love a long time champion. They want to see a guy like Chuck win. MMA is so unpredictable. It seems counterintuative, but this could be the sports greatest limitation.
