"Our family is thrilled for the opportunity given to us by the leadership of the Boston Celtics, but it is emotional to leave a place that we have called home for the past 13 years," Stevens said in a release issued by the university. "We truly love Butler University and Indianapolis, and are very thankful to have had the opportunity to celebrate so many wonderful things together."
At Butler, Stevens was 166-49 — the most wins for any Division I coach in the first six years of his career. In 2009-10, the Bulldogs posted the Horizon League's first 18-0 conference record, a 25-game winning streak and an appearance in the NCAA title game, where they lost to Duke 61-59 when a last-second, half-court shot bounced off the backboard and rim and out.
"Brad has given his talent to our university with exceptional generosity, integrity, and humility," Danko said, calling Stevens "a beloved member of our community."
"We have done everything we can to keep Brad here at Butler; however, the Celtics team has offered Brad and his family a unique opportunity with which no university can compete."
