I saw an Oklahoma fan whining on Youtube about Oklahoma may not make playoff now and I stated that actually the shot is better. One, I think OU will compete in the SEC. Two, you can go 9-3 or 10-2 now with the 12-team playoff and still make it in. OU and Texas, plus SEC, have thought of everything. With the exception of UK and Vandy, anyone in the SEC has a shot and even some of the bad teams are not as far off as you think.
Take 2015 Tennessee for example. They had 2 TD leads on Florida and Oklahoma before blowing them and a TD lead on Alabama in 4th. Had Tennessee not choked (and had better coaching), they could have easily won all 3 games and been playoff bound. You can look through the conference and even see situations and scenarios were Ole Miss, Arkansas, Missouri, South Carolina, etc. make playoffs. To say Oklahoma would never make it is crazy. With a 12-team playoff, they might be in it almost every year because I think Oklahoma will be a top 3 program in the SEC easily.
