re: With more of a deep passing threat, how good can our running game be?

Pre snap reads will get us into better plays consistently based on what the defense shows.

Beyond that, play action will be a much more credible threat than at any time since 2007.

Lastly, and also like 2007, you can expect consistent progressions. No more tunnel vision/stare downs on our primaries. No more pass plays being screwed of the 1st read isn't available.

More poise and cognitive ability fueling decisions. More using eyes and head to move safeties or force them into poor coverage situations. More stepping up in the pocket. Giving the receiver time to get open. Pushing the ball down the field. More stepping into throws.

All of which makes a devastating running game even more effective.
