I too think there are too many bowl games out there, but at the same time, not enough teams considered for the "playoff" and championship. But the Bowls are money makers and it would be difficult to eliminate them, which is one reason they won't expand the post season into a tournament. Not that anyone would ever listen to me, but I think they should actually use the bowl games as the games in a tournament bracket. If I count correctly, there are 40 bowl games, obviously some more significant than others. A 41 team single elimination tournament bracket (including some "play-in" type games) can be made that comes out to exactly 40 games. Or you could bump it to 42 teams and add another bowl. The newer/smaller bowls get the early rounds. The bigger, more established get the later rounds. They can rotate which bowls get the final four and championship games.
All the bowls get to stay, all the bowls matter, we get a tournament.
