Could South Carolina & Vanderbilt Decide the CFB Playoff?

Hear me out.

I think everyone will agree that more likely than not the SEC champion will make the playoffs. With the SECW dominance over the SECE, we all expect the west winner to win the SEC, right? If A&M beats Bama then loses to Ole Miss, and all 3 finish 7-1 then I believe the tiebreaker (6th or so) goes to non divisional opponent record. Since A&M and Bama will have both beaten UT in this scenario while Ole Miss only beat UGA, more than likely it will come down to who finishes higher between USC & Vandy. Assuming I am interrupting the tiebreaker scenarios correctly. What a twisted way to decide such an important tiebreaker.
