That is good but I watched since I had ND +9. ND is better now, but the books still don't respect them. I do not understand the call either and I'm an official. But it is the booth that makes that decision, so you have to go after them on the instant replays. As an official I hate instant reply.
People don't understand how hard it is to make calls on the spot, but its part of the game. Now a days, you might as well have a single official with a headset and every play is called from the review booth.
