I think an eight-team playoff would be a great idea. A playoff is long overdue.
The Football Bowl Subdivision (aka Division I football) is the "only Division I NCAA-sponsored sport without an organized tournament to determine its champion" ( I stole that from Wikipedia).
That's just ridiculous. If the Football Championship Subdivision (aka Division I-AA), Division II and Division III programs can do it, why not the big boys?
I'm sure it's because the NCAA doesn't want to lose all that corporate cash they get from bowl sponsorships.
Why not just make the bowl games the playoff games?
As an example, they could use the Fiesta Bowl, the Cotton Bowl, the Gator Bowl and the Sun Bowl for the four quarterfinal games.
Then the Sugar Bowl and Orange Bowl could be the two semifinal games, and then use the Rose Bowl as the championship game.
The whole process they use now (the BCS) just sucks. It's too subjective.
