Based on running that simulator that Dan posted, and with the results that happened today, and with projecting Illinois to win the remainder of their conference games, that would put Illinois at a 7 seed facing IU in the second round of the BTT.
We get to a 6 seed in that scenario if Michigan loses to Northwestern and Nebraska along with Iowa losing at least 1 of their remaining two games.
With Michigan State's win today, Illinois can not get better than the 7 seed.
Best case scenario for Illinois (in terms of conference record: 9-9.
Purdue, Maryland, Wisconsin, Minnesota, and Michigan State all have 10 wins already, guaranteeing that they will all be higher than Illinois. Northwestern and Michigan both sit at 9 conference wins and have a game against each other. Since one of them will get their 10th win, the winner there will also be seeded higher than Illinois.
Illinois could still theorhetically be as low as the 13 seed as well.
My predictions:
1. If Illinois wins out, Illinois gets the 7 seed and takes on Ohio State, with the winner getting Wisconsin.
2. If Illinois wins one out of two, Illinois gets the 9 seed and takes on Iowa, with the winner getting Purdue.
3. If Illinois loses out, Illinois gets the 10 seed and takes on Northwestern, with the winner getting Wisconsin.
I think Illinois loses to MSU and beats Rutgers, so I'm looking at working from home on the 9th (and maybe 10th) for the early tips in option 2.
