And now......The Rest of The Story...
Kellen Moore’s motion-heavy offense operated within Jason Garrett’s Air Coryell philosophy, placing an emphasis on vertical shots in the passing game centered around a strong run game while HC Mike McCarthy, runs a variant of the West Coast offense that features short, quick passes with little focus on running the ball.
At first glance, it might seem like trying to fit a square peg into a round hole. But these two coaches share a offensive philosophy that goes back to Paul Hackett, the Passing Game Coordinatior, de-facto Offensive Coordinator, under Tom Landry from 1986 to 1988. (The prior three years Hackett had been QB/WR/TE coach learning under the inventor of the West Coast Offense, Bill Walsh, with the 49ers).
With Garrett gone, Moore's primary offensive philosophy is expected to become the one he played in at Boise State under Chris Petersen. Petersen's own philosophy is an hodgepodge of the West Coast Offense he learned in 1992 as QB coach with the Pitt Panthers (University of Pittsburgh), his time under Mike Belotti at Oregon learning the spread offense and his years as OC under Boise State's Dan Hawkins, learning the fly offense, which was built around the jet sweep concept on nearly every play.
Going back to the Pitt Panther team of 1992 where Chris Peterson got his introduction to the West Coast Offense under Head Coach Paul Hackett, there was a third year graduate assistant by the name of Michael McCarthy, coaching WRs. Yes, the same Michael McCarthy who is HC of the Dallas Cowboys today. (The guy we know as BigMac also worked the night shift on the Pennsylvania Turnpike as a toll collector to supplement his income and spent his time in the tollbooth reviewing the University of Pittsburgh playbook).
In 1993 Hackett and McCarthy left the Pitt Panthers for the OC position with the Kansas City Chiefs and offensive quality control coach, respectively. Petersen went to Portland State as QB coach.
Essentially Paul Hackett took the offense he ran with the Cowboys to the Pitt Panthers and taught it to McCarthy working alongside Chris Petersen. And today Petersen's greatest quarterback, Kellen Moore, is the offensive coordinator working for McCarthy.
(Skip Peete, the Cowboys running back coach, was the running backs coach with the same Pitt Panthers as McCarthy and Petersen in 1992).
