Of course, the guys also happen to be on Team USA together -- along with DeAndre Jordan, DeMarcus Cousins, DeMar DeRozan, Kyle Lowry -- and 'Melo organized a dinner for the team.
The squad was all in Vegas gearing up for Monday's first official practice (the team's home base is Sin City) -- but got together at the Wynn Sunday night for a fancy welcome dinner hosted by Carmelo and his friends at Haute Time.
We're told hotel owner Steve Wynn couldn't make it -- but sent one of his favorite magicians to entertain the guys. You can see in the pics they all seem to be havin' a good time.
By the way, big smiles on Draymond Green's face the entire evening -- seems he ain't too worried about that whole assault case in Michigan.
