He's impersonated every huge NBA star ... but if you think Bdot just ACTS like a hoops star you're wrong ... TMZ Sports has video of the comedy star THROWING ONE DOWN in an L.A. hoops game.
It went down during a game in the prestigious L.A. Athletic Club league (where some of the best players in Tinseltown hoop) when Bdot got airborne for a one-handed tomahawk jam off a lob pass.
Check out the clip -- We're not sure if he actually thought he was Russell Westbrook ... but he sure did look like him.
