Based on today's SOR (https://www.espn.com/mens-college-basketball/bpi/_/dir/asc/view/overview/sort/sorrank) , here would be the B1G seedings:
Maryland - 2
MSU - 3
Wisconsin - 4
Ohio State - 5
PSU - 6
Illinois - 6
Iowa - 6
Michigan - 6
Rutgers - 8
Indiana - 8
Purdue - 12 / Last 4 in
EDIT: Regarding what it really means, the SOR has historically been a very close approximator to the committee's seedings, and since it's updated daily, it's a fairly good assessment as to where teams are at at a given moment, especially during tournament time. A particularly interesting team in these seedings would be Arizona, who has suddenly fallen behind Purdue and out of the tournament due to their recent play.
