Sorry for the screw up vis-a-vis PSU/UW earlier.
Deeper dive on potential seeds:
14-5 Purdue, vs IL:
They are the #1 seed regardless of outcomes this weekend.
The six 11-8 teams, UMD, IU, IL, NU, IA, M:
At least one (the IU/M winner) will finish in or tied for second place at 12-8. At least one (the IU/M loser) will finish 11-9. The winners this weekend will all finish ahead of MSU while the losers will finish behind MSU assuming that MSU beats tOSU. The losers this weekend will be tied with each other and Rutgers if Rutgers beats Northwestern. Here are the six, who they play this weekend, and their H2H records against all of the teams that they could potentially end up tied with:
Maryland, at PSU: 1-0 vs IU, 1-0 vs IL, 1-0 vs NU, 0-1 vs IA, 1-1 vs M, 0-1 vs RU.
If the Terps win in State College they will probably get the #2 seed. With a win this weekend they don't have to worry about the 0-1 record against RU because they'll be ahead of RU. They are perfect against IU, IL, and NU and split with M. Only their 0-1 against Iowa could trip them up.
Indiana, vs M: 0-1 vs UMD, 2-0 vs IL, 0-2 vs NU, 0-2 vs IA, 1-1 vs RU (M is not included because they can't tie M).
These are mostly not good. Aside from Illinois, the Hoosiers would lose most ties.
Illinois, at PU: 0-1 vs UMD, 0-2 vs IU, 1-1 vs NU, 0-1 vs IA, 1-0 vs M, 1-0 vs RU.
These are mostly not good but they would win a tie with M, RU, or both so that may set a floor for them.
Northwestern at RU: 0-1 vs UMD, 2-0 vs IU, 1-1 vs IL, 1-1 vs IA, 0-2 vs M, 0-2 vs RU (because in order to tie RU they would have to lose this weekend).
These are mostly not good but they are 2-0 vs IU.
Iowa, vs UNL: 1-0 vs UMD, 2-0 vs IU, 1-0 vs IL, 1-1 vs NU, 1-0 vs M, 2-0 vs RU.
Iowa wins nearly all ties with the possible exception being something involving NU.
Michigan, at IU: 1-1 vs UMD, 0-1 vs IL, 2-0 vs NU, 0-1 vs IA, 1-0 vs RU (IU is not included because they can't tie IU).
This is a mixed bag if I ever saw it.
10-8 Michigan State, vs tOSU:
The Spartans can't tie anybody so this one is relatively simple. If they win they finish behind PU, the IU/M winner, and any other of the 11-8 teams that win this weekend. If they lose they finish behind PU, all six currently 11-8 teams, and RU if they win this weekend.
10-9 Rutgers, vs NU:
If they lose they get the #9 seed. They could end up tied with PSU for 9th/10th but they swept the Lions so they'd win that tie. If they win they will end up tied with NU, the M/IU loser and any other of the 11-8 teams that lose this weekend. Those H2H records are: 1-0 vs UMD, 1-1 vs IU, 0-1 vs IL, 2-0 vs NU, 0-2 vs IA, 0-1 vs M.
What helps the Scarlet Knights is that if they do win, they will be tied with NU and 2-0 against the Wildcats.
9-10 Penn State, vs UMD:
If they win they'd get the #10 seed either as #10 alone or after losing a tie with RU for 9th/10th. If they lose they still could finish alone in 10th place or tied with either Wisconsin or Nebraska, or both for 10th, 11th, and 12th. Their H2H against UW and UNL are 0-2 vs UW, 1-1 vs UNL.
8-11 Wisconsin (@MN) and Nebraska (@IA):
Neither of these teams can be caught from behind so it is simply between them and PSU (if PSU loses) for the #10 through #12 seeds. If they tie each other, Nebraska wins because they won the only meeting between these two.
If Penn State wins, they get the #10 and UW/UNL are #11 and #12. If PSU loses then either of these two could join them at 9-11 with a win this weekend. Wisconsin would win a tie with PSU.
5-14 Ohio State at MSU:
Locked into the #13 seed.
2-16 Minnesota, vs UW:
Locked into the #14 seed.
