Rick Fox Says D'Angelo Russell Deserves a Clean Slate

Rick Fox has a message for anyone still hating on D'Angelo Russell for the Nick Young video -- GET OVER IT ALREADY!!!

We got Fox out at LAX and asked the former Lakers star what he thought about Russell still getting grief over the infamous Nick Young video ... the one that exposed his teammate cheating on Iggy Azalea.

Long story short ... everyone makes mistakes and it's officially time to give the 20-year-old a pass.

Nick seems to agree ... recently explaining, "I can't be mad forever."
