is only really valid against mobile QB's who have good arms. See Jake Locker. A BYU team that lost to Utah St. still managed to beat Locker because they dared him to throw and he couldn't deliver.
If Ole Miss still had Masoli, you'd have a point, but the new guy Brunetti has thrown like 9 total times in his career for 7 yards total. We don't know if he will be good or not, but most QB's when they first start, really struggle to pass the ball. Even the good ones like Landry Jones struggled at first.
