So in my recent stat diving I came to a weird conclusion.
Helton did a better job managing JG than Chaney/Weinke have. Now that's not to say he's a better QB coach or better OC, and the "managing" could also be part of the confidence/mental block that seems now apparent with JG. But most of the issues last year offensively came from the OL, it would have been interesting to see how things went if the OL played as well last year as they have so far this season.
Chaney I'm sure is a "wide open" type of OC/coach, he's likely just not going to limit his offense to suit a QB. Either the QB can perform or he can't, unfortunately it seems JG can't.
