As the preseason for the Green Bay Packers opens on August 9th, Packers head coach Mike McCarthy recently decided not to go with a seasoned veteran to backup Aaron Rodgers at QB. McCarthy believes Harrell could have a great year as the second string quarterback. In the preseason game, Harrell plans on playing majority of the game and is thrilled. But his biggest concern is how to manage the huddle. He is going to have to learn how to make the offense run as smoothly as possible.
