Just a few comments:
1. Why isn't LSU on your list?
2. Georgia doesn't play any other team on the list during the regular season. I would say any of the top15 could go undefeated with their schedule. Georgia is in.
3. USC doesn't play any other team on the list either. But, the 2nd half of their season includes Notre Dame, Washington, Oregon, UCLA and Utah. Three of those teams have legitimate playoff odds but they're not on your list. The other two have longshot odds. USC is losing two regular season games and is not making the playoffs.
4. Florida State plays Clemson and LSU. In addition to Florida State, Clemson plays Notre Dame. One of those teams (Florida State or Clemson) will get in if they have just one loss.
5. Michigan, Ohio State and Penn State all play each other. Only one is getting in and it's not going to be Penn State. I'm guessing Michigan as Ohio State also plays at Notre Dame.
6. Texas and Alabama play each other. But, they don't play anyone else on your list.
7. Alabama beats Texas. LSU beats Alabama. LSU is in.
My prediction: Georgia, Clemson, Michigan and LSU
