Indiana University
When Miller was negotiating a contract extension with Bowling Green in 2005, he included a "dream clause" in which Miller could list a few of his personal destination jobs.[4] The Indiana Hoosiers were on that list and, when an opening for head women's basketball coach occurred at the school in 2012, he applied for and got the position. Miller signed a six-year deal worth $275,000 a year. Miller resigned on July 25, 2014 citing health and family reasons.[5]
While working with the Sun, Miller was "the first openly gay, male coach in college or professional basketball".[15]
