Larry Brown is leaving SMU after turning down a contract extension, ending a four-year run during which the Mustangs made the NCAA Tournament for the first time since 1993 and then were banned from postseason play last season.

SMU athletic director Rick Hart said Friday that Brown, who was signed through next season, had been offered a new deal through 2020.

"This morning, however, I was notified by his agent that he would be stepping down," Hart said. "Coach Brown was able to accomplish so much in his four years on the Hilltop, including leading us to our first conference title since 1993. He has left his mark on SMU basketball, and we are thankful for what he's done."
