Indiana and Tom Crean have parted ways after nine seasons, the school announced on Thursday.

The Hoosiers went to the Sweet 16 three times in his tenure but have not made it to the NCAA tournament twice in the past four seasons -- including this past year despite beating Kansas and North Carolina early in the season.

"After deliberative thought and evaluation, including multiple meetings with Tom about the future, I have decided to make a change in the leadership of our men's basketball program," Indiana director of athletics Fred Glass said in a statement. "Tom Crean brought us through one of the most challenging periods in IU basketball history, led his players to many successes in the classroom and on the court and represented our university with class and integrity."

Glass' statement said that the school is seeking "more consistent, high levels of success."

Crean, 50, took over the program in 2008 after Kelvin Sampson left it in the midst of an NCAA scandal. He had just two returning players his first season in charge and struggled for three seasons.

Things quickly changed during the 2011-12 season, though, with Crean leading the Hoosiers to a 15-win improvement and an NCAA tournament berth. The Hoosiers earned a No. 1 seed in 2013 after winning the Big Ten.

Crean was 148-118 overall and 64-80 in Big Ten play heading into this season, and the Hoosiers got off to a strong start before struggling and finishing 18-16 overall and 7-11 in league play. Indiana lost to Georgia Tech in the first round of the NIT.
