Chris Rock took ANOTHER shot at the QB situation in Washington D.C. -- joking that if he didn't kill it at an awards show in D.C. this weekend, he'd be swapped out for Kirk Cousins.
Rock was performing at the John F. Kennedy Center where Eddie Murphy received the Mark Twain Prize for American Humor ... when he turned the crosshairs on Dan Snyder's squad.
As our friends at ForTheWin pointed out, Rock hasn't been shy about issues with the 'Skins -- back in September he tweeted, "I don't know what's more racist . There logo or there treatment of RG3."
