I can't understand why the Broncos HC continues to insinuate that the team has to reestablish the run to allow the QB to be successful throwing the ball. This is delusionary! Why? Because you RUN or THROW the ball if the OL can open the necessary holes for the RB to go through, or the OL can hold the defensive line from killing the QB. Otherwise, you would need a RB that weights 300 pounds, and can run 30 seconds flat in the 40s to make it through a wall of 300 plus lbs. defensive lineman. You can be successful either way when you establish the run or the pass. You need an OL and OC who can design and diagram the plays either way, to ensure the line can push through to open holes or maintain control of the defending Line to facilitate the pass. This wouldn't work without getting the RB hurt or exposing the QB to mayhem. Either way, the answer lies with the OL being a good line that can excel at both requirements.  Our Ol couldn't open a hole in a paper bag.
