I don't think even Jon and Deace can say with absolute certainty that Iowa wouldn't get left out if we went 13-0. But maybe 98% certainty on it? Sure. The scenario of Bama, Clemson, Baylor and NDU getting voted in ahead of us for reasons already mentioned plus a couple of other scenarios bring the 2% doubt. The 2% doubt comes into play because of the human element of the selection committee-who knows what criteria for sure they're going to emphasize and the human ability to rationalize might come into play as well.
In your doomsday scenario of gigantic "what if" scenarios, Iowa gets in over Notre Dame.
Notre Dame: 11-1, Wins over CFP ranked teams: Stanford, Temple (if they stay ranked), Navy (if they become and stay ranked). Losses to Clemson
Iowa: 13-0, Big Ten conference championship game winners (committee says this is huge on their list), win over a top 10 CFP team (even if Iowa doesn't play Ohio State the team they play WILL be ranked in the top 10 going into the title game). Also wins @NW and @Wisconsin. Either one or both of those teams will be in the top 25 CFP at the end of the year.
- Notre Dame suffers for not being in a conference, so they play 1 less game.
- Notre Dame lost a game. Iowa did not.
- Notre Dame has an overall very strong SoS, but when compared to top 25 ranked CFP teams, Iowa's resume would be equal or better.
- Notre Dame is idle on December 5th while all other teams are playing in their conference title games. We have proof from last year that the committee takes this serious. All the attention given to the conference championship games will cause people to forget that ND beat Stanford the week before. Boo Hoo ND, join a conference.
- Possibly foolish reason but #1 Clemson vs #4 ND is a matchup that's already happened this season. ND lost. It doesn't make sense to repeat it in the first round of the CFP
- An undefeated big ten team will never be left out of the CFP. Ever. The Big Ten would come down on the committee very hard. It would be ugly.
- Barry Alvarez and Tom Osborne love old school football and don't care about "explosive offense". Both of their teams lost to Iowa this year in their own houses. They are also on the CFP committee. Even if Alvarez supposedly "hates" Iowa, he has to respect the season they had. Who on the committee is going to bat for Notre Dame? Tyrone Willingham, the guy they fired?
Is that enough evidence?
