Mike McCarthy won't be the play-caller of the Dallas Cowboys' offense, as previously assumed. Instead, the offensive coordinator of the previous regime will. Kellen Moore won't only be the offensive coordinator; he will also be the play-caller, as McCarthy said on Thursday, via Michael Gehlken of the Dallas Morning News. 

Moore's status as a play-caller should come across as surprising news. McCarthy once went as far as to say that he will never give up that role. He spent the bulk of his 13-year tenure as head coach of the Green Bay Packers as the play-caller, now he will cede those duties to the 31-year-old Moore.

In Moore's first year as OC in 2019, the Cowboys ranked as the NFL's top yardage offense and sixth-ranked scoring one. Though Dallas failed to reach the playoffs — finishing with an 8-8 record — the former backup to Dak Prescott and Tony Romo impressed in his first year managing the offense.

Moore received interest in the offseason. The University of Washington pushed to make him their offensive coordinator. However, according to Ian Rapoport of the NFL Network, the Cowboys' commitment to keeping him as the play-caller ultimately sealed his fate as the offensive coordinator in Dallas.

The Cowboys' 2020 offense should be a blend of McCarthy and Moore's philosophies. Expect McCarthy's West Coast schematics to find itself in the playbook. However, there will be a lot of the same, which means continuity for quarterback Dak Prescott and the rest of the offense. If Moore's offense finds success, he could be the next hot head coach candidate.
