Nebraska is considered on the bubble, right now. If they win out and go 14-4 and win their first BTT game I think they are in.
If they lose ONE of their next 4 games I think they are out. They play nobody the rest of the way and a loss will really hurt them. They would either be losing a home game to an average team or a road game to Illinois. Yikes. Winning them all isn't a big help but NOT losing may keep them above the cut line. Too many variables to be certain. A notable BTT win would be a must in this scenario.
The ONLY team they've beaten that will be in the tournament is Michigan, from what I can tell.
They lost by 23 to St. Johns!
