NFL.com news: Up-tempo Colts plead for adjustments to umpire position rule
Eventually the Colts won't be the only one complaining. The umpire right now lineups in the backfield with the referee, except for the last 2 minutes of each half when the umpire returns to his original spot with the linebackers. However, other teams will start to plead and complain come the regular season. When they're down by multiple scores with 5 minutes left in the game, the offense goes to run their hurry up/no huddle offense then, and the umpire is still in the backfield with the referee, slowing the offense down.
