The Big 12 could easily shoot itself in the foot by having two successful top 10 teams in Baylor and TCU. It is very possible that both will get left out of the playoffs. Here is how I see things playing out for the rest of the season for the top teams.
Alabama. Oregon and Florida Stare each take care of business the rest of the season, and wins their conference championship. they get the 1,2 & 3 spots in the playoffs.
This leaves Mississippi State, TCU, Ohio State, and Baylor fighting for the last spot.
TCU plays at Texas and vs Iowa State. I see them winning both of these and ending the season 11-1
Ohio state has home games vs Iowa and Michigan. I see them winning both of theses and getting into the BIG10 championship game. If they win this they will be 12-1
Baylor has home games against OK State and K. State, and a road game at Texas tech. the only challenge here is K. State, but since it is in Waco, I see Baylor winning and being 11-1.
Baylor has the tie breaker with TCU and would be Big 12 champs.
I can’t see the selection committee passing up on an Urban Myers coached 12-1 Ohio state for Baylor or TCU.
Mississippi state would be out of the picture because they will be left out of the SEC championship.
In this case the Big 12 will have the #5 & #6 teams, but no spot in the playoff. The conference expansion talks would heat up BIG TIME, and who would be at the top of the list? Hopefully BYU.
