tom crean is 120-107 overall (49-75 Big Ten) in seven years at indiana, has two ncaa tourney appearances, and has finished better than fifth in the Big Ten only once. last year, he finished tied for eighth. this year, seventh. he's likely to miss the tourney again this year.
and he'll almost surely be back for an eighth season.
oscar probably has similar job security, we just don't know it yet.
