GREEN BAY, Wis. – Tenths of a second matter to coach Mike McCarthy and his offense. It’s why during training camp the Green Bay Packers use a clock that’s set at 2.5 seconds and counts down each time the ball is snapped.
If the clock hits 0.0 and the quarterback still has the ball in his hand, a siren sounds and green and red lights flash.
It’s McCarthy’s version of a shot clock.
If it were allowed on the sideline during games this season, the Packers would be sick of the sound and tired of the lights.
