Lionel Hollins has received permission from the Memphis Grizzlies to talk to other NBA teams about a head coach opening.

Discussions between the Grizzlies and Hollins stalled on Saturday night, with "major philosophical differences," according to a source.

The Brooklyn Nets will primarily target Hollins and Brian Shaw for their coaching vacancy.

Hollins led the Grizzlies to the Western Conference finals and has said he wants to return.
