Bucks hire new head coach shortly after dismissing Adrian Griffin

The news comes less than 24 hours after the Bucks made the surprising decision to part ways with first-year head coach Adrian Griffin at the midway point of the season.

Griffin had led Milwaukee to a 30-13 record, tied for the second-best mark in the league, but there were questions about his schemes on both ends of the court and his ability to connect with the Bucks players. The franchise felt that replacing Griffin with a veteran head coach could improve the Bucks’ title chances, sources tell Wojnarowski.

Rivers reportedly served as an informal consultant of sorts for Griffin beginning last month, at the behest of the Bucks, and immediately emerged as the team’s top choice once the head coaching position opened up on Tuesday.

Rivers, 62, has enjoyed a long head coaching career that includes stints with the Magic, Celtics, Clippers, and Sixers. He has a 1,097-763 (.590) regular season record and a 111-104 (.516) mark in the postseason, including a championship with Boston in 2008.

While Rivers has long been considered one of the NBA’s top head coaches, his playoff track record has been spotty since that ’08 title with the Celtics. His teams made the postseason in 15 of the 16 subsequent seasons but advanced beyond the second round just twice during that time. Rivers was let go by Philadelphia last spring following a third consecutive second-round exit.

Rivers joined ESPN as an analyst following his stint with the Sixers, but will step away from that job in order to attempt to lead Giannis Antetokounmpo and the Bucks to their second championship in the past four seasons.

The terms of Rivers’ contract with the Bucks aren’t yet known, but it’s expected to be a “very lucrative” deal, sources tell Chris Mannix of SI.com. As Mannix observes, Milwaukee is now dedicating a significant chunk of money to the head coaching position, since the team is still paying both Griffin and former coach Mike Budenholzer.

It’s unclear how soon Rivers will be on the sidelines in Milwaukee. The Bucks host the Cavaliers on Wednesday night and again on Friday — assistant Joe Prunty will serve as the interim head coach until Rivers arrives.
