McCarthy's arrival will bring an entirely new offense to the Cowboys after running mostly a Garrett scheme since 2007 even though the team has had three different playcallers since 2013 in Bill Callahan ('13), Scott Linehan ('14-18) and Kellen Moore ('19).
Moore, offensive line coach Marc Colombo, quarterbacks coach Jon Kitna and receivers coach Sanjay Lal are under contract. Most of the defensive staff, including coordinator Rod Marinelli and passing game coordinator Kris Richard, have expiring contracts.
