I think that the Pro sports have the right idea. Break College Football into divisions (conferences) and then give each winner a berth plus have a couple wild cards.
How this could work in College Football:
8 Team playoff
6 Conference Champions
2 Wild Cards.
Hell, let's make it interesting and have play in games. So 4 wild cards, but only two advance to the actual playoffs.
Now, here is how this would work schedule wise:
All regular season schedules must be complete by the last weekend of November. This includes conference championship games. This would push the start of the season up a week or two, but there are two good reasons for that. First, players would be arriving at school a month or two early for practices, and programs could be "encouraged" to set up mandatory tutoring for students who are not maintaining a high GPA. Second, fewer games at the end of the academic semester when finals come around.
Now, the play in games would take place on the third Saturday of December, or three weeks from the end of the season. The four teams would be ranked, and the higher seeds would host the lower seeds. During those three weeks practice time would be cut in half for the first two weeks (allowing players to study and take all final exams in this time frame), with expanded practice times the week before the game.
The playoffs would start on New Years Eve, with two games happening that day and two games on New Years day. These games would be also be hosted by the higher seed. The second round would take place two weeks after that, at neutral sites. The Championship game would take place two weeks later, again held at a neutral site.
Thus, the season would end a week or two into second semester, and only two schools would have students miss any class time during second semester. The neutral games would rotate between a couple different warm, southern cities.
Also, bowl games could still be played for everyone else (including playoff teams who lost in the first round), held the before the first round and between the first and second rounds (depending upon how good a team is).
The Brewers will finish 95-67 and win the NL Central.
Mat Gamel will finish with a .280/.340/.440 triple slash. He will also hit 30+ HR and drive in 90+ RBIs (prorated if plays less than 150 games).
