Forget that College Playoff Rankings crap. I like my postseason better.
I've done this for a few years now. My playoff is 12 teams where the champs of the big six conferences are automatically in, the top ranked champion from one of the other conferences and then five at-large bids (no more than three teams from one conference allowed). I seeded them by using the now-defunct BCS standings.
With the new way of college football, there is no BCS standings (I'm using a variation of that for this exercise) and there are now a big five conferences and not six. So, we will use the champs from those five leagues, the top champ from a non-five league and then six at-large bids.
And here is what I got:
FIRST ROUND BYES
1-Florida State (ACC champ)
2-Alabama (SEC champ)
3-Oregon (Pac 12 champ)
FIRST ROUND GAMES
12-Marshall (CUSA champ) at 5-TCU 6p
11-UCLA at 6-Baylor (Big 12 champ) 9p
10-Kansas State at 7-Ohio State 3p
9-Michigan State at 8-Ole Miss (Big Ten champ) 12p
SECOND ROUND GAMES
Michigan St/Ole Miss at Florida St 9p
Ohio St/Kansas St at Alabama 12p
Baylor/UCLA at Oregon 6p
TCU/Marshall at Mississippi St 3p
