There's only one way to spin 2015: and that is to go into it with no expectations. Be happy when they win, and find a few positives when they lose. Enjoy going to Kinnick, having a brat and burger and beer at a tailgate. Enjoy the weather when it's nice.
But have NO expectations to win, not even a single game. And then you will be less likely to be disappointed.
That being said, I see us most likely going 5-7 next year. So yeah, enjoy those 5 wins as much as you can, and enjoy whatever you can at the other 7, whether it's a brat, beer, or whatever.
