This is wrong on like 3 different levels.
1. Even if Oklahoma loses to Oklahoma State, if Navy+Pittsburgh+Temple+USC all lose this week then we're stuck without any good wins and will get passed by someone like Baylor (or even Oklahoma State).
2. Notre Dame's clearest path to the playoffs actually has nothing to do with Oklahoma.
2A. Iowa losing to Nebraska and MSU losing to PSU has a much greater chance of putting ND in the final four than Oklahoma.
2B. The least likely but overall best chance of ND getting in is for Alabama simply to lose to Auburn this week.
3. The game isn't over, but it's close. Saying a 2 score game is "over" with 20 minutes+ to play is silly.
1. I highly doubt the committee would punish ND, if the beat Stanford, for their opponents losing. They haven't been punishing other teams for it. It's unreasonable to think that if ND has an impressive win over Stanford, but their opponents have a bad week, that the committee would look down on ND.
2. This is simply wrong. It's been acknowledged for weeks that OU is ND's biggest competition. The scenario you laid out requires three games to go ND's way (Iowa, Sparty, and OSU all losing), while with OU, you only need one game to go your way. OU losing is the simplest/easiest/most realistic path to ND making the playoff. It's really not even disputable. Baylor wouldn't jump ND after having a (potentially) less impressive win this weekend, and the committee isn't high on OK ST due to their cupcake schedule. If ND wins and OU loses, I will wager any real/vbuck amount that ND is in.
3. Given Navy's complete inability to stop Houston on offense, it wasn't a huge reach at all to say the game was over. They've gotten one stop all day, ffs.
