TCU and/or Baylor got hosed. (and I'm an Ohio State fan).  Had TCU/Baylor gone in Ohio State would have been screwed.  So here's how to solve the problem.  An 8 team playoff.   That part doesn't solve the problem.  This part does.....

 

Make it a playoff of conference champions.   You want in?  Win your Conference.  Didn't win your conference?  You are not in.  

 

There are 10 conferences and 1 set of Independents (which includes Notre Dame)

 

Seven of those conferences are a step above the others.  They are:

 

1. SEC
2. ACC
3. Big 10
4. Big 12
5. PAC 12
6. AAC
7. Mountain West
 
Those 7 conference winners automatically get in.  Then you have some system to pick one other conference champion from 
 
Conf USA
MAC
Sunbelt 
Independents
 
As far as seeding, I would only seed 1-4.  And draw their opponents randomly.  That way one conference (AAC for example) doesn't get perennially "judged" to be the weakest and therefore faces the #1 seed every year.
 
This system is specifically NOT designed to pick the best teams.  If you do that it becomes a beauty contest and you have the same arguments every year.  This system is designed to crown a national champion from conference champions.
