Hard to say. Henning has been lauded as great with QBs and average as a coordinator but that seems to be based on his Jets experience, because the O did better when he was QB coach than when he was OC. As an OC I don't think he fully used Martin the way he could have, and the D wasn't as good so pounding Martin the way most teams would, that didn't work as well because teams weren't behind.
He's a guy who fits what Fix wants. He's steady, he's fundamental, he's deliberate. He creates mismatches, just as any veteran coach would, he runs the ball a good deal and takes shots deep when they're available. So therefore he'll start out as a God.
Will you like him? Probably not. I know how it works, I've seen it before. By November half of you will be complaining that he's not innovative enough and too predictable.
