Dak Prescott, the Dallas Cowboys and Third Level RPO/Packaged Play Reads

Dallas Cowboys rookie Dak Prescott had about as good of a preseason debut as any rookie could ask for: Prescott finished the game 10 of 12 for 139 yards and two touchdowns, including a perfect strike to receiver Terrance Williams down the sideline. But as impressive as that throw was, Prescott’s most impressive trait was his calm and poise: In an opening weekend when higher profile rookie QBs like Jared Goff and Carson Wentz looked at times shaky and off-kilter, Prescott looked like a vet. So while there’s no need to get the hype train rolling too fast — it was one preseason game, and Prescott was facing almost entirely backups and guys who likely won’t make the roster — it was a great start.

But, even if Prescott plays great, all he can do is solidify his spot as the backup QB behind Tony Romo, which is why the most interesting play to me was one that told me something about what the Cowboys will do even when Prescott’s not in there. Specifically, on Prescott’s first touchdown pass, a ten-yarder to Dez Bryant, Dallas head coach Jason Garrett and offensive coordinator Scott Linehan called a “third level” packaged play, also known as a run-pass option or RPO. Third level packaged plays are the newest (although not that new) step in the evolution of shotgun spread “read” concepts: When the shotgun spread first became popular in the late 1990s and early 2000s, the defining plays were the zone read and read-option plays, in which the QB read a “first level” defender, i.e., a defensive lineman. The big innovation by the end of the 2000s and early 2010s were, first, built in screens, and later the earliest packaged plays/RPOs in which receivers ran slants, hitches and sticks and the QB would read a “second level” defender (i.e., a linebacker or nickel defensive back playing like a linebacker) to determine whether to hand off or throw.

In recent years a few teams — most notably Baylor, although there are others — began using packaged plays where the quarterback read a safety to determine whether to hand off or throw. This had two primary effects: (1) it is an excellent response to Quarters coverage, in which the safeties read the offense to determine whether to play the pass or the run, often outnumbering offenses in the run game as they are so difficult to account for; and (2) it transforms a read concept that was originally designed to move the chains by having the QB either hand off or throw a screen into a handoff or a touchdown.

Which brings me back to Dak Prescott’s play against the Rams. There was nothing that sophisticated about the concept: The Cowboys called an inside zone run play, in which they blocked all of the Rams’ frontal defenders, including the backside defensive end (i.e., no read option element), and tasked Prescott with reading the safety to the side of the single receiver, who just happened to be Dez Bryant. Now, I’m not sure if Bryant was only allowed to run a fade or had some sort of choice in what route he’d run (either choosing on the fly or via a pre-snap signal between receiver and QB), but teams often adjust the route by the single receiver to find the way to best attack the safety.

In any case, given that it was Dez Bryant singled up, all Prescott really needed to confirm was that the safety wouldn’t be able to help, something he was able to do quite quickly and likely even pre-snap. (A savvier safety might have aligned inside and then hurried back outside; Prescott did stare down Bryant a bit.) And with an extra safety stepping up for the run and a freak of nature 1-on-1 near the goal line, Prescott’s choice was simple:

So while Prescott’s performance should give Cowboys’ fans hope for what they might see in the future, this play should give them some insight into what they might see this season: A cutting edge concept that, in the end, reduces to a winning formula: Run the ball behind that great offensive line with extra numbers, or throw it to #88. That makes sense to me.
