David Griffin remains in the final year of his contract as he and the Cleveland Cavaliers were unable to agree upon an extension.

Griffin first assumed general manager duties in February of 2014 following the dismissal of Chris Grant.

Griffin has been responsible for signing LeBron James, as well as trading for Kevin Love, J.R. Smith, Iman Shumpert, Channing Frye and Kyle Korver. 

Griffin has received the support of key voices inside the Cavaliers' locker room, most notably James.

"It makes no sense why he shouldn't get an extension," James recently told ESPN. "He's pulled every move -- he's tried to make every move happen -- to better this team to be able to compete for a championship. So we wouldn't be in this position, obviously, without him and without the guys that are here -- from the coaching staff to the players to Griff. He's been a big piece of it."

Ty Lue, who shares agent Mark Carmony of CSE with Griffin, also recently spoke out about what the Cavs GM did this season.

"Griff's done a hell of a job," Lue said. "To acquire D-Will 2 [Derrick Williams], D-Will 1 [Deron Williams], [Kyle] Korver and [Andrew] Bogut without having any money, that's an amazing job. Griff's done a tremendous job. Every time someone goes down. Even last year, the year before when Timo and J.R. and those guys came in, he just always seems to work his magic when we need it and he's done a great job. Now it's my job to make sure I put everybody in the best possible way to be successful."
