Yes.

But as counter evidence I present the smoke draw and option to the short side of the field.

During the game, Dickey is up in the box looking at the things that Jimbo can't see. For example, Dickey will look at something in the front 7 while Jimbo is watching the safeties or vice versa. Jimbo will ultimately decide what play to run, but you can guarantee he is relying on Dickey for a significant amount of input when he makes his decision.

And playcalling absolutely does matter no matter how much talent you have. If you want to debate that, go watch reruns of the last 5 years of our offense under Spav and Mazzone.

From what I understand Dickey helped implement some of the RPO wrinkles and newer downfield passing elements(air raid). Jimbo's used them before, but it's more about how well those elements synergize with the other principles of the offense(i.e. zone run blocking, WR option routes, QB called blocking protections, etc...).

A weakness of the Mazzone offense is the defenses could dictate the play from their own alignment as they'd force our QB to make the read he was supposed to and then blow up the play. There's even an ESPN segment of Bama's front 7 reading run/pass based on our OL alignment where the Center dictated the blocking.

With Jimbo's Offense they had no idea when a zone read was coming and couldn't force a specific read because Mond had other keys to read off of. It's also why Jimbo's offense has reputation of perhaps being the most difficult system to learn in college ball for QBs. Mond's making reads and calls for every position in the offense. It's daunting but the offense modulates to attack actual defensive exposures over perceived reads. With Dickey, D-Coordinators can't just dust off the old methods of stopping the option and TE seams because the new wrinkles will come into play.
