After playing 10 games last year, Crawford used a medical redshirt because of a torn labrum in his right shoulder. He could have transferred to another program by taking advantage of the NCAA rule for fifth-year graduate students.
Crawford's decision was made tougher when Bill Carmody was fired after last season. Crawford had been recruited by and played under Carmody for four seasons. Carmody recently was replaced by Chris Collins.
"I can't wait to be on the court with my Northwestern teammates again this upcoming season," Crawford said in a statement. "Coach Collins has brought great energy to the program and we all believe in his vision. I have loved my experience here at NU and I'm proud to call it home. I'm ready to do all I can to lead this group and make my last year at Northwestern a great one."
