"The Browns were in a no-huddle offense trying to get to the line of scrimmage to snap the ball and stop the clock. Things were moving very quickly. When the pager went off (just before the snap), the referee allowed the play to take place before confirming with the umpire and the replay assistant that he was paged for a review." If the refs really got it right, they would have blown the play dead before the snap of the ball. By allowing the play to go on, they made a mistake.
