That is the damned point. Harbs has not grown. He has remained the exact same poor game mang guy he was when he started. He doesn't have the pulse of his team.
This is very similar to Joe. I liked him when he was drafted. He was doing so much well from the start. But after about 3 yrs I noticed he was the same. There was no expanded understanding of the game. At that point I switched to it is time to go. With harbs around the same time I noticed the same kind of issues. Now I only see him as an anchor. Until such time as he can fix those oblivious issues he is the weak link.
