Grizzlies coach Lionel Hollins was informed Monday evening that his contract would not be renewed, thus ending his reign as the most successful leader on the bench in team history, sources told The Commercial Appeal. Hollins’ contract is scheduled to expire June 30 but the Griz have decided to go in a different direction because of “philosophical differences,” according to sources close to Griz management. Under Hollins, the Griz reached the Western Conference Finals after winning a franchise-record 56 games in the regular season. The franchise improved its record every season Hollins was coach. The Griz will now consider former Denver coach George Karl and former Phoenix coach Alvin Gentry, along with Griz assistant coach David Joerger as a replacement, according to a source with knowledge of the team’s plans. Joerger is widely believed to be the frontrunner to replace Hollins because the front office views him as an up-and-coming, potential star coach. Joerger’s salary also would be far less than what Hollins, Karl and Gentry would command. That’s significant because there is a belief among some people in the Griz front office that similar results could be achieved without a high-priced coach. Hollins, meanwhile, is a candidate to become the head coach of the Los Angeles Clippers or Denver Nuggets. He will interview with both teams later this week.
