"The specter of an NBA lockout combined with the Grizzlies' obstinate negotiating manner could cost them another assistant coach by the weekend.

Johnny Davis, the lead assistant coach under Lionel Hollins, reportedly has an offer to join the Toronto Raptors in a similar role once his Griz contract expires at midnight. The Griz are working to retain Davis but an agreement hinges on the length of a deal, according to sources with knowledge of the situation.

Davis, along with Hollins' entire staff, worked last season on a one-year deal without a raise from the previous season. Davis has been paid the going rate for lead assistants given his pedigree as a two-time former NBA head coach. But he will have an opportunity to receive a raise and more job security with Toronto, according to a source with knowledge of the Raptors' interest.

NBA.com first reported Toronto's interest in Davis.

Davis' departure would mean that Hollins will start next season without at least two members of a coaching staff that engineered the Grizzlies' most successful playoff run. Assistant coach Damon Stoudamire left last month -- soon after the Grizzlies' Western Conference semifinals appearance -- to join Josh Pastner's University of Memphis men's basketball staff.

Stoudamire is credited with impacting player development and influencing Zach Randolph's improved professionalism.

Davis oversaw the Grizzlies' offense and served as a calming and constructive influence on the bench during games."
