I'm a sucker for top 10 lists. I find I can learn a lot about a sport by just watching their "Top" whatever videos. I've seen some things in MMA that make me scratch my head as to why the fight was called in such a way. I remember the older days where it really felt like it was an outlaw sport - no rules, no limits etc. Since then, the sport has polished up a lot, and I don't blame officials for making these calls. Some of these moments are pretty intense. Viewer discretion is advised. Can you add any other moments that changed the rules of MMA forever?
