Nick Young Wants Everyone to Back Off D'Angelo Russell

Nick Young has a message for anyone still giving D'Angelo Russell grief ... cut the kid a break ... saying his Lakers teammate -- who taped that bro-code violating video -- is "good" with him.

TMZ Sports got Swaggy leaving Toast in L.A. and asked how he felt that people are still razzing Russell about the whole thing ... heckling him at a recent Drake concert at Staples with chants of "HIDE YOUR PHONE!!"

You might remember ... Young has publicly said he's trying to move past the incident 'cause he "can't be mad forever" and from what he told our camera guy ... he wants the rest of the world to as well.

BTW -- He also revokes his banishment of Chris Brown from their neighborhood ... something we're sure Brown didn't give a damn about in the first place.
