Minnesota.
It's one thing to keep winning when you can't afford to lose a single game. It's another to go out there and win this kind of means nothing game after the type of championship game loss they had.
Plus ESPN keeps previewing this as both teams playing for some degree of respect/recognition of the level of their programs...so it makes too much sense for Missouri to lose.
Also, Minnesota is kind of the Mizzou of the B10 only they've been doing it a good while; they flirt with having really good seasons but usually lose the big games that would raise their program.
