Could see this in watching our 1st offense in the past few preseason games... there's mistakes being made but not many by Luck. The rest of the offense isn't as progressed as Luck in picking up the playbook and no-huddle. This will come over time. But just watching, it was obvious Luck wanted to do this or that, and the other end of the transaction "wasn't ready", wasn't where they were sposed to be.
I think it's a good sign... Luck's absorption of the playbook is impressive, so we have nothing to worry about there... he'll be ready when the rest of his team catches up. It also means that this offense will make some big strides forward this year as guys start to put it together and Luck is able to do what he wants to do. You can tell he has a Manning-like grasp and sense of control, but right now he's herding cats.
