Liddell and Couture made over a million @ 57, Gracie pulled in over a million @ 60 - Hughes might have even pulled in a mil. Shamrock and Ortiz pulled in over a mil at 61. It's not the purse for a million, but rather a percentage of the PPVs which combined with the purse equals over a million.
First actual million dollar purse - definitely won't be Liddell-Silva. Probably won't be happening anytime soon.
