Cary Williams recently called out the 49ers as "pretenders" and "dirty" on an ESPN radio talk show. There's also an article on NFL.com which has a video with good alternate angles of the skirmish following the Kaepernick interception. Check out the video on the NFL.com link at 0:31. You can see Cary Williams punching Alex Boone in the gut and maybe lower while Alex Boone is pinned on his back by another Ravens' player.

For him to call the 49ers "dirty" when he tries to pull this type of stuff off, is ridiculous. I hope someone calls him out. The tape doesn't lie. He's complaining on radio about getting his helmet pulled off and supposedly getting kicked by Bruce Miller (@ 0:26 on the video). That kick by Miller looked inadvertent as he was in the process of being dragged off the pile by another Ravens' player, but Williams dirty play is on display with great clarity and camera angle for all of the world to see.

He should learn to shut his mouth and check his own behavior before calling out other people.
