T3 Bracketology has them on the "Almost Flat Bubble"
BIG TEN
Locks: Purdue, Indiana, Northwestern
Should Be In: Rutgers, Illinois, Iowa, Maryland, Michigan State
Bubble: Wisconsin, Penn State, Michigan
Almost Flat Bubble: Nebraska
Northwestern moved into lock status from a bubble position after its latest fantastic stretch of basketball. Rutgers, Illinois, Iowa, Maryland and Michigan State all sit in a position where it will take a lot to miss the field, but not a full lock yet. Wisconsin and Penn State remain firmly on the bubble, and Michigan's win over Michigan State pushes them up to the bubble as well, but still out of the field. Nebraska will need to win its next four games, at minimum, to start to have real berth conversations, but the chances are not at 0%.
