Imagine if Draymond Green, Boogie Cousins, John Wall and other NBA stars rolled up on your pickup game and asked to play ...
That's EXACTLY what happened in the Bahamas on Wednesday -- when a group of young ballers got one helluva surprise ... and the whole thing was captured on video.
Cousins was the first guy to walk over ... and despite the fact he was in flip-flops, he grabbed the ball and challenged some of the men to a 1-on-1.
Draymond -- sporting a fanny pack -- followed suit ... along with fellow NBAers Wall and Eric Bledsoe.
Wall is currently nursing a ruptured Achilles tendon he injured back in January -- we should mention that we never see him actually competing in the footage from the Bahamas.
We're told the guys stuck around for about 30 to 45 minutes and couldn't have been nicer to everyone.
Unclear why the group is in the Bahamas -- but word in Nassau is someone is getting married.
These guys have all been friends for years -- with Boogie, Bledsoe and Wall playing college ball together at Kentucky before making it to the NBA.
... and they became friends with Draymond somewhere along the way.
