The Cleveland Cavaliers' general manager David Griffin is in the last year of his contract with the team, and there is a chance that the Cavaliers will not offer him an extension. LeBron James, the team's biggest superstar and best player, wants Griffin to stay in Cleveland and hopes the Cavaliers will offer him an extension.

"It makes no sense why he shouldn't get an extension," James 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."

Cavaliers failed to extend his contract last year

The Cleveland Cavaliers wanted to extend David Griffin's contract last season, but they failed to come to a mutual agreement. This could be a big issue if both sides don't agree to a new contract soon, as Griffin will be unemployed and there is no doubt a lot of teams will want his services after what he has done in Cleveland.

Griffin has been the Cavaliers' general manager for over three years and he's been with the team since 2010. Before the Cavaliers, he spent 17 years working for the Phoenix Suns, where he is originally from. Even though he refused to comment about his contract situation and a possible extension, it is very likely that he wants to stay in Cleveland as he has had a lot of success running the franchise.

David Griffin has done a great job in Cleveland

In just three years, David Griffin has pulled some fantastic moves for the Cleveland Cavaliers and he turned them into a championship contender. Shortly after being named general manager, Griffin brought LeBron James back to Cleveland and he orchestrated the trade for Kevin Love, who was one of the best power forwards in the NBA.

Because of these moves, the Cavs' GM finished second in NBA Executive of the Year voting, and his team reached the NBA finals.

LeBron James said how Griffin always gave his best to help the team and he showed it this year as well. Griffin pulled one of the biggest midseason trades a few months ago by bringing Kyle Korver to Cleveland.

He also signed Deron Williams, Andrew Bogut and Derrick Williams without having much money to work with. David Griffin is undoubtedly one of the best general managers in the entire league and his team recognizes the amazing work he has done. Hopefully LeBron's endorsement will help him get a contract extension as he's been an invaluable part of the team ever since he became GM.
