How much will Cowboys' offense...

The change will affect the Dallas Cowboys' offense, which will be without Kellen Moore for the first time in seven seasons. How much will the Cowboys' scheme alter now that Mike McCarthy is in charge of play-calling?

"Right now, Mike told me [around] a 20-30% difference," quarterback Dak Prescott told Yahoo Sports during Super Bowl week from Arizona. "I believe there are things that should be changed.

"It's fantastic to dial in, adjust certain problems, and get sharper and crisper. "I'm ecstatic." On Jan. 29, the Cowboys and Moore announced a "mutual parting of ways," less than 24 hours before the Los Angeles Chargers revealed Moore will be coordinating their offense and developing outstanding third-year quarterback Justin Herbert.

So the Cowboys seek a different voice, an at least partially different scheme and some different offensive philosophies. Cowboys team owner/general manager Jerry Jones and executive vice president Stephen Jones attributed Moore’s departure to the philosophical differences between McCarthy and Moore.

Should an offense attack opponents with deep, extended routes to stretch defenders vertically? Would quicker short and intermediate passers increase the success rate? How often and in what scenarios should receivers run option routes, perhaps stressing a defender more acutely but also risking the receiver interpret defensive cues differently than the quarterback who needs to anticipate the throw?

How much is changing for Cowboys, Prescott and Moore?

The Cowboys' front office will also likely look to upgrade Prescott’s receiving corps a year after trading top wideout Amari Cooper (and his $20 million salary) to the Cleveland Browns in exchange for a fifth-round draft pick.

Wide receiver CeeDee Lamb posted 1,359 yards and nine touchdowns in his first season as a true No. 1 receiver. But the Cowboys’ pass-catching corps otherwise struggled, as fifth-year receiver Michael Gallup was unable to return smoothly from an ACL tear while third-round rookie Jalen Tolbert played just 16% of offensive snaps and caught two passes for 12 yards.

Decisions face the Cowboys' front office on multiple offensive starters as Pro Bowl running back Tony Pollard hits free agency, franchise-tagged tight end Dalton Schultz is likely to command more on the open market than Dallas hopes to pay, and veteran running back Ezekiel Elliott enters his first year with zero guaranteed salary. A pay cut is a near certainty should Elliott desire to stay with the Cowboys. Even with a pay cut, his return is no sure deal.

Who will lead the Cowboys' offense in 2023?

Jerry Jones knows his team fronts a defense that is the Cowboys’ best in more than a decade. With defensive coordinator Dan Quinn returning to Dallas for a third season, Jones believes McCarthy has the freedom to dial in more closely on running and calling the offense.

“Frankly, I want Mike and Dak to join at the hip on the execution at quarterback,” Jerry Jones told Yahoo Sports from the Senior Bowl earlier this month, “Mike of course knows the personnel, knows [Dak], so picture if I had just interviewed him and he was coming in, how far ahead he is of making this thing really work.

“Knowing Dak and what he’s going to do, and knowing Mike, I think we’re definitely going to see positive, positive, just a lot of positive results.” McCarthy promoted veteran coordinator Brian Schottenheimer, who spent 2022 as a consultant for the Cowboys, to offensive coordinator. McCarthy’s first NFL opportunity came from Schottenheimer’s father, Marty, from 1993-96 with the Kansas City Chiefs.

Brian Schottenheimer coordinated the New York Jets' offense from 2006-11, the then-St. Louis Rams' offense from 2012-14 and the Seattle Seahawks' offense from 2018-20. During Schottenheimer’s Seahawks stretch, with Russell Wilson at quarterback, Seattle ranked top-10 in scoring and top-five in passing touchdowns all three years.
