Considering the Wings signed one of the biggest divers in the league this offseason and Kesler is still in the league, I think Brown is safely out of the top spot.
You forgot what he is most prolific at though....Diving. He's fighting with Ribiero for the title of "king of the flop".
Brown unfortunately is prone to Maltby like antics, embellishing crosschecks and willing to take a punch to the face to draw a penalty, but I wouldn't even put him in the top five for diving in the league. It's just annoying he does it at all because unlike the 4th liners who do it, Brown has a lot of great qualities to his game.
