Billy Donovan and the Oklahoma City Thunder have agreed to part ways, the team announced Tuesday.
Donovan joined the franchise ahead of the 2015-16 season after a lengthy stint at the University of Florida. In each of Donovan's five seasons, the Thunder had a winning record and had a winning percentage of more than .570. He won more than 60% of games as the team's head coach.
Despite co-winning the National Basketball Coach's Association's Coach of the Year award this year, the Thunder allowed Donovan's contract to expire after the team's playoff loss to Houston.
