Its all about selling tickets and PPV
Couture is loved by fans, Timmy is rather hated.
The UFC knows on any night Randy can win (well any fighter can really) he just has a better shot in a title match. They couldn't set up Mirko Vs. Tim, Tim Vs. AA 4, or Tim vs. Vera (because of Veras leaving)
This doesn't really leave much... Randy out shines any of the 3 names I didnt just say. Fans will back Randy in this one and to be honest I'm glad to see he gets a shot, if he wins he will truely go down as one of the greats for his preformances in title matches.
My 12 fighter army is as follows:
Mirko "the man" Filipovic
Fedor and Aleks
Q. Rampage Jackson
