For the first time since leaving Florida to coach the NBA’s Oklahoma City Thunder in 2015, Billy Donovan is on the move.

On Tuesday, the Chicago Bulls announced they have hired Donovan as their new head coach. His contract expired with the Thunder at the end of the 2019-20 season, and he and the team decided to not pursue an extension.

“We are very pleased to welcome Billy and his family to the Chicago Bulls. The success that he has sustained over the course of his coaching career puts him on a different level,” Bulls executive vice president of basketball operations Arturas Karnisovas said in a statement. “We feel his ability to help his players reach their potential, both individually and collectively, will mesh well with our roster. Whether as a player or as a coach, he has won everywhere his career has taken him, and we hope that will continue here in Chicago.”

Donovan’s stint in Oklahoma City marked his first coaching job in the NBA. Over five seasons, he led the Thunder to a 243-157 record, reaching the playoffs all five years. However, after guiding Oklahoma City to the Western Conference Finals in his first season in 2016, Donovan and the Thunder lost in the first round each of the past four years.

This season, Oklahoma City lost to the Houston Rockets in seven games in the opening round of the playoffs in the NBA bubble at Disney World.

Donovan had tremendous success while coaching Florida from 1996-2015, leading the Gators to back-to-back national titles in 2006 and 2007. He also guided them to four SEC Tournament championships and six SEC regular-season titles, while winning the SEC Coach of the Year Award three times.

While it was possible that Donovan could have decided to return to the college ranks, he’ll instead stay in the NBA and try to lead the Bulls, who have missed the playoffs four of the past five years, back to success.

“I’m excited to partner with Arturas as we work together on behalf of this historic franchise,” Donovan said in a statement.
