Out of curiosity, is the time you're referencing time in the pocket, or snap to release in general? I'd also argue that the low QB hits are partly due to Tyrod's skillset as well. In my head I see it as roughly 60/40 on whether holding the ball is a detriment to the OL or assisting them.
To add, I do not list the OL as part of what's hindering our passing game. I think they play off Tyrod as much as he plays off them, and they generally compliment each other quite well.
