The pac 12 should take a look at their divisions if their is such a disparity.
Stanford shouldnt lose to Oregon in the regular season if it wants to for to the cg.
Let's use your model on last year's 4 teams surviving their CCG. After their 12 game schedule, these are the 4 teams the committee has in:
Alabama, Washington, Clemson, Ohio State.
SEC: Undefeated and already in the playoff,
after their 12th game, Alabama played a bad Florida team and the consensus going in was that 12-0 Alabama was in the playoff even if they were upset in the SECCG. SECCG, tits on a bull.
Pac 12: Washington vs Colorado. The consensus 2nd best team was USC. The Huskies were already voted in the playoff at #4 before their CCG
after their 12th game. but had to play a weak Buffalo team. Nothing to win, everything to lose. Pac 12 CCG, tits on a bull.
Big 10: Penn State vs Wisconsin. Didn't matter, Ohio state was already ranked in the playoff
after the 12th game and got in after their CCG. B1G CCG, tits on a bull.
ACC: Clemson vs VaTech. Much like the Pac 12 CCG Clemson had everything to lose and nothing to gain. They were already ranked in the Playoff
after the 12th game. The Hokies were 3rd in the conference with 2 losses while a one-loss Lousiville team would sit at home. ACCCG, tits on a bull.
Big 12: Didn't matter. Neither qualified for the playoff just like the Big 10 CCG. And like the B1G neither was ranked in the playoffs
after the 12th game. Big 12 CCG, tits on a bull.
Now you can talk for an hour on how you would fix it, but this is the reality. This last season is a version of what college football fans have to put up with in the CCG every year.
Conclusion: The CCG, tits on a bull.
