Brown is a grabber. The NFL ref's get film each week and they see the calls they should have made. His reputation precedes him so even when he doesn't grab the guy, or it was mutual like with the Josh Doctson play he was flagged on, the ref's are going to call it on Brown. It's like a great baseball hitter like Wade Boggs taking a strike, the Ump assumes he's right.
I told you all last year that he has bad instincts and grabs whenever he gets into trouble. That's very hard to coach out of a DB. He's not a starting CB and some of you are slowly finding that out.
