There is an exclusiveness factor here. The first game is well attended because it equates to what is only a one game scenario now. You cannot argue that the prospect of three games does not alter travel perceptions. Maybe not as many people go to game number one because of the other two games. You are looking at this like there is a vacuum or something.
No, I'm not.
Any fans that you lose because this is now
one out of a potential three-game trip are more than made up for by the number of fans you gain when the game changes from meaningless bowl game to national championship playoff.
Respectable football programs play in a bowl game
every year, and fans still attend the bowl games. You cannot seriously believe that fans who otherwise would have attended a meaningless bowl game would choose not to go to a playoff game.
