Cowboys' Christian Parker Outlines Defensive Scheme and Expectations

Parker made it clear that the Cowboys will be multiple on defense. However, the base scheme will be a 3-4. He's bringing over some of his Philadelphia roots as the Eagles run a 3-4 with the flexibility to shift into a 4-2-5.

That differs from what fans have seen in recent years as Dallas primarily worked in a 4-3 under Eberflus, Mike Zimmer, and Dan Quinn.

"The first thing is we're going to be multiple. I think that whenever you form a defensive structure, it's about the players that you have," Parker said. "So our core principles, we'll be a 3-4 by nature, but 4-3 spacing will be appropriate, 4-2-5 in nickel, different front structures, coverages behind it. But I will say being multiple is probably the most important thing about it."

The Cowboys struggled to consistently rush the passer last season. Only two players on the roster finished with 5.5 or more sacks. Jadeveon Clowney led the way with 8.5 sacks, but three of those came in the regular-season finale.

Parker believes having success against the run early and pressuring opposing quarterbacks on money downs is essential.

"Definitely stopping the run and affecting the quarterback are the two most important things you can do," Parker said. "You affect the quarterback by stopping the run… When you have teams in 3rd-and-2s and 3rd-and-3s, usually those aren't the defenses that are as successful."

"But if you can win first down and you're strong on fundamentals, we're getting off blocks, we're tackling, we're attacking the football, we're situationally aware, those are the ones that are successful," Parker added.

One of the aspects that Parker likes about the 3-4 scheme is the versatility it allows on defense. Dallas won't be limited by its usage of a vast number of personnel.

"You can be multiple, the body types that you can provide for the team, you can get different types of interior linemen, outside linebackers," Parker said. "You get in different front structures, four-down, five-down, six-down, three-down, and it just kind of feeds into the demeanor of how you want to play from a personality standpoint with speed on the field."

Parker's vision is just starting to take shape in Dallas.

It's up to the Cowboys to provide him with the necessary pieces in free agency and the NFL Draft.
