Two words: Ranking System.
The UFC needs there own ranking system so there is always a clear cut number one contender that will fight for the title.
Problem is they don't want to adopt one because that would stop them from having all control in creating the match-ups they want for more 'exciting' fights in their eyes to sell more PPVs.
Sad that Dana and company want to legitimize MMA as a sport and have it in the Olympics but fail to create a basic ranking system that any other legitimate sport has.
