If there is a playoff, the bowls will come to an end within 10 years of the playoff system starting. There will be no interest in them. Neutral site games are not realistic for a football playoff system because most of the alumni of any school can't afford to travel to more than one bowl game a year, let along 2-4 playoff games. The stadiums would have a lot of empty seats as it is hard to find 85,000 fans in any city willing to go watch a game they have no interest in.
Speaking of neutral site games, I see the PAC 10 is going to play their championship game at one of the schools in the championship. I think this is a great idea and something the MAC should look at doing again. Nothing says "small time" like the thousands and thousands of empty seats in Detroit. Play at a smaller stadium and the empty seats won't look so bad. If the PAC 10 can do it, the MAC can do it.
In the above brackets, there are only three games there that would be worth the time watching. The first round wouldn't be much different than the first round of the NCAA basketball tournament.
They should play the MAC Championship game @ Fawcett Stadium in Canton.
