I posted something similar to this in the BCS thread but it kind of got lost in the mix there. A lot of the talk in that tread and in most college football discussion is about a need for a play off and how unfair the system is to choose a national champion. I would argue that there is less wrong with the actual BCS selection process and more wrong with the regular season. Now don't get me wrong I love college football because the regular season matters so much, but I think it could use some improvement.
For example OSU took a lot of heat this year for having a soft schedule and many argue that is a big factor why they even got the play for the national championship. This argument pops up from time to time (USC a few years ago, Oklahoma) and could easily be fixed. In college basketball there is the Big 10/ACC challenge. I propose that a similar concept be adopted by college football except that the challenge would rotate. So for example the first year it would be the Big 10/ACC, SEC/Big 12 and the PAC 10/Big East. Then the second year it would all rotate and be something like ACC/SEC, Big 12/Pac 10, Big East/Big 10 and so on. This would guarentee that every school from a BCS conference plays a team from another BCS conference. If you win your conference one year you will play the conference champion of another conference the next year. If you finish second you will play the second place team, etc. From a logistical stand point you could say all of these games will be played the 3rd week of the season and set up the rotation a head of time so you know you will be playing a home or road game and just figure out the opponent at the end of the season. You would get some really exciting games and be guarenteed of having all conference champs from the previous season playing each other on the same day in the early season.
My second proposal would be the require all conferences go to 12 games and have a conference championship. Now I hate these games, but since some conferences have them and aren't getting rid of them we may as well make it fair and add it to all. I know the argument is that it will mess with tradition and rivalries. Well if it makes the overall sport better I think we can all deal with it.
With these two changes to the regualar season it would be very hard to say you had an unworthy opponent in the BCS title game. I'm not saying it would elminate controversy but it certainly beefs up the competition and adds a lot more exciting football games.
