They are supposed to be going to school.
Also, the chance of injury against top flight competition increases, and huge rewards worked for a lifetime could be lost.
Just my opinion, but I’m satisfied with 4 teams. If they would simply take conference winners only into the tournament, they’d also increase the importance of conference play. Expand each conference to 16 teams, and you accommodate most of the Div I football schools.
As a hypothetical, it doesn’t really matter to me if Auburn is better than Oregon, if Florida has already beaten Auburn. By this format I’ve suggested, every game becomes important, every conference becomes important.
All other college football conferences (Division I AA, Division II and Division III) have playoffs.
It’s ONLY division I A that does not in ALL SPORTS period. Every other sport, including football at all levels, have a playoff system.
The existing bowls can be used as the playoff system. Which I think is a win win since it will bring a lot more interest in bowls that normally do not get much attention.
