It was really a two dog race and you have to wonder if Brock Lesnar vs. Randy Couture could’ve beaten Oscar De La Hoya and Manny Pacquiao if the previously rumored Spike multiple episode previews which would’ve been much like HBO’s 24/7 series, had happened.
Also, UFC’s December show will probably jump in there anywhere from number 6 on down and bump out the UFC show headlined by B.J. Penn and Sean Sherk. However, I think that Tito Ortiz definitely helped that buy rate.
UFC is the king of PPV. I imagine the next WWE show on that list is probably Royal Rumble or something, but it has to be fairly down that list.
