"They hold up a card on the sideline, he kicks his foot and they snap the ball. That ain't playing quarterback. There's no leadership involved there. There might be leadership on the bench, but when you get them and they have to use verbiage and they have to spit the verbiage out and change the snap count, they are light years behind."
