draw a lot of fouls and that at times he (yes, like MANY other players) throws his hands up at contact and exaggerates the contact to try to get a whistle? The kid is an amazing player but there have been times that (even as a fan) I've rolled my eyes and thought that I would swallow my whistle if I were officiating because he's gilding the lilly a bit too much.
I saw the Haws "mugging" on the replay and while there was contact I wasn't convinced that him going to the floor was actually caused by the contact. Just my $.02, and the one thing I thought that could explain a no call in that situation.
