This would
reduce the number of college football teams playing in the post season. No, that is not a misprint.
But notice he doesn't say do away with the bowl games. This could be in addition to some of the bowls, which then may need even more teams to fill them up.
The field of 68 for the b-ball tourney is currently based on 344 teams while there are about 1/3 that many 1A football teams. So 32 should be the max, with 16 being a more manageable number, given the fact as Medina mentioned that you can do only one game a week.
Something that should also be fixed is the ability of schools to hire coaches from other schools whose teams are in bowl games. It's really unfair for teams to have to play a bowl game with a different coach than the one who got them there.
