Indiana beat Purdue again today (throttled Purdue, rather). 41-14 combined score in the first two games.
Iowa and Michigan also already won today.
4:30PM CDT standings (RPI, SOS, Quad one wins, B10 games remaining):
1. Indiana, 29, 78, 6, (Purdue 1gm, @Mich St 3gms)
2. Maryland, 53, 64, 7 (Minnesota 2gms, @Penn St 3gms)
3. (tie) Iowa 34, 85, 5 (Mich St 1gm, @Northwestern 3gms)
3. (tie) Rutgers 44, 76, 1 (Illinois 2gms, @Minnesota 3gms)
5. Michigan 118, 102, 3 (Northwestern 1gm, @Ohio State 3gms)
6. Nebraska 115, 166, 2 (Penn St 2gms, @Purdue 3gms)
The top 4 are the only one with a chance to do enough in the regular season to earn an at-large bid into the NCAA Tournament. Michigan and Nebraska will need to do more in the Big Ten Tournament to have any hope.
Note: None of the top 6 teams have games remaining against any of the other top 6. In other words, not many major challenges left.
