Purdue and Wisconsin are locked in to the 1-2 seeds. Purdue probably will be the 1 as they hold the tiebreaker.
Minnesota and Maryland are most likely to be the 3-4. Minnesota holds the tiebreaker, but Maryland has @Rutgers and Sparty left, with Sparty at home, I think they finish 12-6 to get the 3 seed. Minnesota finishes at Wisconsin, so likely they finish 11-7. If Michigan wants that 5 spot they have to win Wednesday. That 5 spot is crucial, as it sets up to play the winner of the 12-13 game, likely to be ohio state, Penn state or Indiana. Then they would most likely get another crack at Minnesota which I am sure the team would relish.
A lot of basketball left, but Wednesday is huge.
5 through 7 is where it gets interesting. Sparty currently is 9-6, but will be underdogs in all 3 remaining games. I think they finish 10-8. NW and Michigan are 9-7 and play each other Wednesday. Both could finish 11-7 but lose the tiebreakers to MD and Minnesota.
