Though I agree its a bad idea, I think riding the superbowls coattails might just give them some big recognition. Not entirely sure about it, but it could work. If they try it then that will probably be our UFC supershow, likely planning Fedor/Couture and Jackson/Forrest for that one. I say Forrest becasue hes a big name for UFC fans.
I think having the event the day before is a good enough attack plan for UFC. On Super Bowl weekend Vegas is always going to be packed with people and they'll need something to watch while they're there the night before the game.
