I think it is a little premature to dig Frost's grave just yet.
First off, who is to say Northwestern isn't simply f*cking good this year and maybe one of the best teams they play this year? I don't see Ohio State or Michigan State on their schedule. And who is to say we are not even better than them, let's see how things go.
And guys, if we don't recover the onside kick (slippery hands, a funny bounce) or if a ref make a bad call or if the Nebraska QB drives them down the field at the end, we lose. It's not like we won by 21 points. Nebraska could have most certainly won this game.
If they win the next two and even if they lose the Oklahoma game, I can see them going undefeated the rest of the way or only having one loss, against, say Michigan or Wisconsin. Or both, but that is still an 8-4 season, Bowl game, progress.
Mind you, am I predicting that, but is it out of the question, most certainly not.
I can see him going 9-3 and keeping his job and even 8-4 and keeping it.
