The Dallas Cowboys are hoping Mike McCarthy can get the most out of a talented roster. McCarthy is still getting acclimated to his personnel.

The former Green Bay Packers head coach said he has had to do the most learning in terms of Dallas' offensive scheme, including protection. McCarthy also noted he retained a lot of the passing concepts from last season.

Indeed, the Cowboys do not need much of a makeover on the offensive side of the ball.

Dallas ranked second in the NFL in terms of offensive DVOA, per Football Outsiders. Quarterback Dak Prescott had the best year of his career, while Ezekiel Elliott rushed for over 1,300 yards and 12 touchdowns.

Kellen Moore had some good success in his first year as offensive coordinator, and Prescott should have some additional weaponry with rookie wideout CeeDee Lamb joining the receiving corps.

Of course, the Cowboys will be lacking one of their most productive stars up front.

Five-time Pro Bowl center and former first-team All-Pro Travis Frederick shockingly announced his retirement after just six years in the league. Frederick had been a staple particularly in the run game.

Fortunately, the Cowboys have three returning starters on the line, and McCarthy will work with some of the younger players filling in at center and left guard.

Dallas is coming off a 2019 in which it went 5-8 in its last 13 games to miss the playoffs for the second time in the last three years.

Jerry Jones will look for McCarthy to get up to speed in a hurry as the Cowboys hope to return to the playoffs.
