As you stated, we won.
I think it actually takes a good team to win these type of games.
I think BYU is a good team — much better than the average CBer is giving them credit for. I do think we are making some dumb mistakes on the field and on the sidelines.
I don't think that Notre Dame or Arkansas are "unwinnable games." I think that notion is ludicrous. It was even ludicrous before the season when we thought they were both Top 10 teams. Neither are.
It is frustrating as a fan to see your team not play to its potential and it coaches not put them in a position with scheme or playcalling to do so, but the sky is not falling. And next year will not be a disaster: we have so many weapons around our new QB next year that we'll be OK (maybe not good yet, but OK).
