Bargen led Butler to considerable success in men's basketball in his eight years as head coach, including six years of 20 or more victories, two conference titles, a regional championship and two trips to the national tournament. Dozens of former players went on to play at four-year institutions. Butler twice won 29 games in a season (2010 and 2015) and this year broke the school's modern-day record with 22 consecutive victories.

"In addition to winning, Coach Bargen also handled himself and his program in a first-class manner," athletic director Todd Carter said. "We are certainly saddened to see him and his family leave Butler, but we also understand this is a fantastic opportunity for him and we wish him all the best."

An immediate search for Bargen's replacement has begun. Assistant Ben Walker has been promoted to interim head coach.
