No way you can do 12 teams. 11 conference champions and 1 wild card.
So the wild card would naturally be the #12 seed, which is going to be a 1 loss SEC team.
If you do the 11 conference champs, actually 10 conference champs now the WAC doens't exist.
So 10 conference champs, with 6 wild cards.
Odds are the seeding would be something like this in most years:
1. SEC
2. Pac12
3. Big 10
4. Big12
5. ACC
6. MWC
7. AAC (Big East)
8. C-USA
9. MAC
10. Sun Belt
11. SEC #2
12. Pac12 #2
13. Big10 #2
14. SEC #3
15. ACC #2
16. Big12 #2
#16 @ #1
#15 @ #2
#14 @ #3
#13 @ #4
#12 @ #5
#11 @ #6
#10 @ #7
#9 @ #8
In the situation listed above, Wyo could potentially be hosting a Top 10 team in LSU, or Alabama in Laramie, because we won our conference and they did not.
Same as the NFL really. The Chiefs are likely to have the 2nd best record in the AFC yet be a 5 seed.
It puts a lot of emphasis on being the best team in your division (in this case, conference).
The winner of the 1/16 and 8/9 play each other, the winner of the 2/15 and 7/10 play eachother and so on.
It would be extra important for teams falling in the 7-10 range to finish strong and not rest anyone as they want homefield advantage. I know if you are western kentucky, you probably don't want to have to go to somewhere cold like Fort Collins, Logan, or Laramie for the first round.
This way, the little guys get their shot, and the big conferences still end up with the most teams in it.
Higher seed gets home-field until the National Championship game.
Just imagine the big boys for once, having to go to a small school, and for a game where it matters.
Plus, that way, you don't hear the same old crap about the small schools and how they would get killed if they had to play a hard schedule week after week.
When it comes down to the post season, the best team will have to win, week after week.
