We all know the problem. How do you pacify the BCS Bowl's and at the same time have a realistic playoff? The "plus one" really does not work. Last year,Florida, Texas, and USC all lost 1 game and Utah went undefeated after their respective bowl's were played. So once again, we are down to an election. Not only that, but a "plus one" eliminates a BCS Bowl game because the current NC game would be replaced with a game featuring two teams that have already won a BCS Bowl. Alabama would not have gone to the Sugar Bowl if the "plus one" was in place. That means that undefeated Utah may not have even received a BCS Bowl bid. So the "plus one" actually created more problems than it solves. You would have to take a non BCS Bowl game and turn it into a BCS Bowl game to equalize everything out.
An 8 team playoff could have major problems, especially if the BCS Conference Champions are automatically included. Let's look at last year. One loss teams who did not win their conference include Texas and Texas Tech. Then you have undefeated Utah and undefeated (before the bowl games) Boise State to deal with. Two teams do not get into the playoff, and controversy runs rampant. To add on to potential future problems, you have the Notre Dame situation. Now what do you do? Expand to 16 teams? That would mean that you would have to cut the season down by at least 1 game. A lot of very good teams would lose a ome game, and the revinues that go with it. Then, you have to realign all the bowls, unless you have the first round games hosted by the team with the better record, but then you have another controversy. Who decides who is ranked where? The voters, ofcourse.
As much as I would love to see a NC game, I simply have not come up with a doable playoff system yet. My best guess is to simply to with 8 teams and run it like the pro's. The 1-4 teams get home field advantage for the first round, with the two highest ranking teams getting another home game. When we are down to two teams, do the bowl pairings. To do this, the schedule would have to be changed so that the first two rounds would be played during the first two weeks in December, and the bowl season would start at it's normal time. I can not come up with anything else, and I doubt that my system would meet with a lot of approval.
