If the Dallas Cowboys hire Dan Quinn it’s a clear indication that they would be looking to keep the team in a base 4-3 defense, the scheme Quinn has run throughout his career. Dallas struggled mightily to adjust to Mike Nolan’s new scheme which, while still technically a 4-3, also disguised things by often utilizing many of the concepts that a 3-4 defense uses. Nolan’s scheme was far more complex and a big shift away from what former defensive coordinator Rod Marinelli ran for six seasons with the team.
As the roster stands now, the Cowboys’ personnel likely best fits into a base 4-3 and it was pretty evident as they looked most comfortable when running that this past season. With a top 10 pick in the draft, Dallas will have their choice of high upside players who can make an impact on defense. That’s good news for a team that sported the worst defense in team history this past season.
