At the end of the day the actual purpose for a playoff is to separate record from ability to finaly DETERMINE who is the best and who is not.
This narrative that "the best teams" are already known before the playoff starts is just dumb.
Until the playoff begins all you really have to go on is record, SoS, and quality wins/losses. Dwags have 2 losses, and no wins of any real significance. Their best W is probably us. Notre Dame is undefeated and while they didn't play as hard a schedule, the top wins they have are arguably just as good as dwags wins. Yes dwags played tougher schedule, but the couple games that made it clearly tougher, they lost; one they got stomped in.
So regardless of who the eye test says is better, one team is undefeated, the other has 2 losses and one to a team that's already in. Dwags had their chance and blew it. It's time for someone else to get a shot. This is much like us vs Michigan in 06. No one thought we could win but mich had the chance and blew it. Then look what happens in the game! Do I think Notre Dame is good enough to win? Probably not, but no one's been able to prove that narrative about them so far. Dwags on the other hand...
And just for the record I hate note dame but the purpose of a playoff is to actually determine who's best, not pre-determine who is. A 2 loss over an undefeated with similar quality wins? Please....
