David Stern -- Obama Should Be NBA Coach ... I'll Represent Him!

With only 2 years left in his term, President Barack Obama should start planning for his next job ... and according to David Stern -- his first post-presidential gig could be NBA coach!!!

The ex-commish was leaving a State Dinner at the White House with his wife Tuesday night when we asked if he had any tips for B.O. when his term's up in 2016.

Stern's response: "Yeah, I'm gonna represent him ... he's gonna be a COACH!"

Stern wasn't the only sports figure at the State Dinner ... Kevin Johnson and Jason Collins were there too.

The Menu -- Guests dined on some pretty awesome food ... including caviar, quail eggs, 12 varieties of potatoes, a winter garden salad, dry-aged rib eye beef, chocolate malted cake made with bittersweet chocolate from Hawaii and tangerines from Florida and served with vanilla ice cream.
