So your original premise is that great coaches don't lose games that they should win or have won. Then it's, great coaches can lose those games, but it's rare. You're then alluding to the fact that we've been "sold a bill of goods" and that Rhule isn't a great coach because he lose a game that he had won, despite the fact that this is his first game at NU and he doesn't have a history of losing games that he had won in his career (making it rare that it ocurred).
I just think that a lot of Husker fans need to take a step off of the ledge. It's one game. A game that on paper and to most outside of the state of Nebraska, we were supposed to lose, and lose by a touchdown or more. It might be an exception or it might be the norm, but to extrapolate one game to being the end of Husker football as we know it seems to be an exercise in insanity.
