To me, the answer is as simple (well, not so simple...) as this....
Alabama BEATS Auburn and sCam Newton....
Oregon loses to Arizona or Oregon State
Then you have only 2 undefeated teams: TCU and Boise State.
If they both are IN the National Championship game, you will have enough uprising that they do not play a tough schedule so the inclination will be that the ONLY way to rid of these pesky teams is to force them into a playoff....
If they are NOT in.... government gets involved and the BCS will absolutely be declared in violation of anti-trusts laws (which it clearly is anyway).
