Listening to the Tournament Selection Show, Hollis said how difficult it was for teams to move up seed lines the past few days. So it seems likely that Michigan entered the B1G Tournament as a 9 seed --- safely in the bracket --- and slid up 2 seed lines over the course of the weekend.
I'm not trying to defend MSU's seed, but the Sparties lost to a bunch of top-seeded teams early in the season while injuries played a major impact on its roster. MSU went on to post a better in-conference showing than we did.
So fair to assume both entered play on Thursday seeded on the 9-line. Michigan won and was able to move up; Michigan State split its games and stayed put? Logical responses from the committee when looked at that way.
As for Minnesota, another team seeded a line or 2 higher than I thought, but clearly the committee has a lot of respect for Vanderbilt --- Minny's early season win over Vandy probably looked better to the committee than it did to you or me, plus its B1G regular season mark and you can see the logic for that seeding.
