I don't think tonight will get us to a 7. I'm not even sure tomorrow will. It's hard to jump so much so late in the game. That said, NU is only a nine seed now because a bunch of "experts" say so. It's possible the committee thinks of NU differently. My feeling on this:
LOSE TONIGHT - 9 seed
WIN TONIGHT - 8 seed
WIN TOMORROW - 7-8 seed
WIN SUNDAY - 7 seed
Yes, it seems like winning the Big 10 should be worth more than that, and the team will get a little boost for being "hot," but I'd be shocked if they jumped so many teams this weekend.
