Why doesn't Harrison throw a fit when he's being held?
James Harrison should throw a fit in front of the ref whenever he's being held, since it seems like it's happening on nearly every play. If he did that, the backfield ref would probably be more likely to call more holds. If he doesn't see Harrison complaining, then he assumes Harrison has no problem with the way the tackle is playing him. I don't understand why Harrison doesn't complain more often.
