A coach upstairs should have the power to say in the headset to Harbaugh, “Call a timeout! New England’s doing something we can’t identify!” Or something like that. But it’s not up to the referee to give the defense an unlimited amount of time. Seven seconds is enough for a defense to match up. In this case it was simply a great use of trickery by the Patriots, and the players weren’t giving much away in the locker room after the game. Asked about the formation, several replied vaguely, and with no details about what happened, or when it was practiced. Belichick has trained them well.
