Team USA Basketball -- Attempts Beach Volleyball ... Fails. (VIDEO)

You'd think a bunch of super tall, super athletic rich guys with beach houses would KILL IT at beach volleyball ... but you'd be wrong.

Here's Kevin Durant, Klay Thompson, DeAndre Jordan and the rest of the Team USA hoops squad taking a break from the hardwood to mess around on the sand.

A bunch of Kerri Walshes they ain't.

Still, good to see the guys blowing off some steam and having fun before the medal rounds.
