From nba.com:
The Oklahoma City Thunder are promoting assistant Mark Daigneault to become the team’s next head coach, per ESPN’s Adrian Wojnarowski.
Daigneault, 35, makes the rise after Oklahoma City and former head coach Billy Donovan mutually agreed to part ways in September.
After a two-month coaching search, the franchise ultimately decided to hire from within. Daigneault has been with the franchise since 2014, mostly serving as head coach of the G League Oklahoma City Blue. He previously worked as an assistant under Donovan at the University of Florida.
Daigneault, who will become the second-youngest head coach in the NBA, takes over a team with promising young talent and several Draft picks in the coming years. Rumors of Thunder guard Chris Paul being traded has swirled, which would only import more assets for Daigneault to lead.
With the hire, there are currently no more coaching vacancies.
