I agree that most of us have zero idea of how to play QB. However, there is no being hyperbolic with noticing that in many instances, receivers were wide open. Fans noticed it and all of the reporters noticed it. Didn't you?
Fact is, he is a below average thrower, well below average. You mention Book who also rarely went past his first read. You also said he was more accurate. I would say much more accurate. Also, Book was recruited as a backup. RL, on the other hand, was bought with big money. As for the growing pains, people talk like RL is a developing QB. Well, would you spend big time money to get a 1 year QB that needs developing? So far, he has been a "swing and a miss". If you disagree, please explain why cuz nobody else can see it.
