So where does that leave the 42-year-old? Vogel has a .580 winning percentage in the regular season and a 31-30 record in the postseason in his six seasons in Indianapolis.

Frank Vogel is out in Indiana. Pacers president Larry Bird announced Thursday that Vogel wouldn't be back as head coach at the end of his contract, which expires after this season.

Vogel transferred to the University of Kentucky in 1994, where Donovan was an assistant under Rick Pitino from 1989-94. Vogel was a student manager at UK in 1994-95, Donovan's first year as a head coach at Marshall.

“Both of us working for Coach (Rick) Pitino, there’s a relationship there," Donovan said Thursday at Thunder practice. "When I left Kentucky, Frank had come in after so our time never really crossed over at all."

When Pitino went to coach the Boston Celtics in 1997, he gave Vogel his NBA break as a video coordinator. Vogel was promoted to Celtics assistant coach under Jim O'Brien in 2001.

With head coaching positions open in Sacramento, Houston, and with the New York Knicks, there's no shortage of options for Vogel entering next season. He's a coach with clear defensive chops that took the Pacers to the playoffs five times in six seasons – the one season they missed the playoffs in 2014-15, All-Star forward Paul George missed 76 games following a horrific leg break playing for Team USA.
