Offensive Line issues may be exaggerated

To start the season, sure. But you'd expect the guy to improve as the season goes on, right?

I would have expected him to enter camp with the proper footwork and hand placement down pat after spending all off season working with an OL specialist. I might have expected him to enter with better flexibility in his hips and with a better center of gravity. But nope. I am really curious why the man is incapable of grasping the fundamentals.
