Here's one scheme I saw for a 16 seed playoff. All 11 FBS conference get 1 automatic bid with the remaining 5 at large.
Doesn't look like much of an improvement to me and so much of the excitement and drama of the regular season is robbed. You probably have to give up a CCG and 1 regular season game for this system. The top teams still cruise through Sun Belt, MAC, or C-USA teams first round and then play a few games that are CCG caliber anyway to get to the NCG.
That playoff format is a farce. There is no way you're going to take ONLY the top teams from each conference. A 16-team format is the only way to go, with some poll mechanism being used to determine the teams. Yes, there will be griping from team #17, but the case for the 17th team is FAR worse than the case for the #3 team in the current format. Even in a plus-one format, the #5 team often has an argument as legitimate as team #4. As you go further down the polls those arguments lose legitimacy, making a 16-team format the ideal solution.
A four-round playoff would not ruin the current format of games. You could start the last week of August, play your 12-week schedule, then have your playoffs. There is no reason to eliminate games, and the regular season's games do not become watered down because only slightly greater than 10% of your teams can actually make the playoffs. Yes, two teams will play a 16-game season, but that's only one game more than Villanova and Montana, the two teams in the D2 Finals last year, played.
If we could break these ridiculous bowl game ties from these conferences we could have a playoff. It's simple, it's been done for years by D2, and it makes sense. Enough with the BCS. Enough.
I'll disagree with knapp a little this format is ok, however it needs a lot of tweaking. Conf. usa, the MAC, and Sun Belt should not have automatic spots in the tourny. Alos I would say you add a minum reocrd lets just say 9-3 to get in. The more qualifcations, the more clear cut, the less contoversy. I'm afraid the point is moot, no matter what solution there will always be a new problem. This is the only level of footabll that does not have a playoff and no matter how good of systems that gets sugested it's probably going to stay that way for a long time to come.
