I'm not buying the "lack of practice reps" excuse.
We had 83 yards of total offense at the half, with King at QB for all but the first series. He looked lost, just like a kid who hadn't had many reps in a while.
Then the light began to go on in the second half. His lack of practice reps didn't stop him from raising his game.
He just needed to be thrown into the deep end, and to let him figure out how to swim.
