I really dont think it's in the best interest of any organization to try to strong arm the Nevada State Athletic Commission. Organizations go by their will, not the other way around.
You might recall from WAAAAAAAAAAY back when Josh Barnett got busted for steroids following his win over Randy Couture at UFC 36.
UFC dropped him and his license to fight in Nevada was suspended for like a year and a half. PRIDE wanted to scoop up Barnett immediately. NSAC said if you want to hold an event in Las Vegas in the Future, you better abide by our judgement on fighters.
PRIDE a MUCH bigger organization than the UFC at the time, didn't sign Barnett until his suspension was up.
So yeah, don't try to move the 900 lb gorilla.
