The Cowboys' other notable defensive roster moves included drafting outside linebacker Malachi Lawrence in the first round, signing veteran outside linebacker Von Miller, signing veteran defensive tackles Otito Ogbonnia and Jonathan Bullard, drafting inside linebacker Jaishawn Barham and signing veteran safety P.J. Locke.
Parker has been working to utilize that personnel in a transition from a 4-3 to 3-4 base defense that is expected to cause problems by keeping opposing quarterbacks uncomfortable.
"One of his really premium goals is to mix it up and be unpredictable," Cowboys owner Jerry Jones said on 105.3 The Fan before their preseason opener in Seattle. "That really takes a lot of communication. That takes a lot of coordination. Bottom line is, I think he's got all the ingredients. Not only is he a motivator, communicator, but he's got the ingredients to be a very strategic outstanding coach."
Parker's hands-on coaching style has been witnessed throughout practices going back to rookie minicamp. Many have talked about his ability to relate to players with examples going beyond what is seen on the field.
"I think it's important when you're communicating in the heat of the moment, the relationships matter," Schottenheimer said. "There are a lot of times where you are making a correction, and if you don't have the relationship, if you don't have the buy-in from the players at times, players, coaches as well, can tune you out.
"I don't think there's any chance of that happening, because he's built up a rapport with these guys."
Schottenheimer has often talked about the individual time Parker has been spending in his office with players going over film. There were far too many communication issues last season. The extra time should help eliminate those carrying over into this season.
"If you don't have that, I think it hurts your ability to critique, coach, coach hard and call out," Schottenheimer said. "They need to know you love them and care about them. So, if you don't spend the time doing that, you're missing an opportunity.
"I think (his youth) does help. I didn't go to three nights straight of Jay-Z (concerts) in New York City. He did. Four or five of our players were there. … I do think that the age does help. They are into the same things. He's got some really expensive shoes. He's got some really expensive watches. And so do our players. … That's real. That's real that you can relate to your guys like that."
While Parker has been seen working with many, no one appears to be getting more [individual time than rookie Caleb Downs](https://twitter.com/jonmachota/status/2083655169531871603). The first-round pick is expected to be one of the biggest factors in Dallas' defensive turnaround. He will be deployed in a variety of ways as a do-everything defensive back who can help in all areas. One play he could be stepping up to stop the run or blitz the quarterback and the next he could be dropping into coverage against a wide receiver, running back or tight end.
Defensive back is Parker's speciality. He was a cornerbacks coach when he got his start in college at Virginia State in 2013. After moving up the college ranks, his first NFL job was a defensive quality control coach with the Green Bay Packers before becoming defensive backs coach for the Denver Broncos in 2021. The previous two seasons were spent as the defensive backs coach and defensive passing game coordinator with the Philadelphia Eagles.
The defensive backfield should be much improved with Parker's coaching and the personnel upgrades. But will they have enough pass rush in his first year as a defensive coordinator? That's where his coaching will see the biggest test. Can he find consistent ways to scheme up things to make opposing quarterbacks hold the ball a little longer?
It certainly sounds like he has no problem putting in the extra hours to figure it out. His preparation and attention to detail has been a common theme when others have talked about Parker.
"I don't even want to talk about that," Parker said when asked about how little sleep he gets. "It's not something I'm necessarily proud of. But the job has to get done and you kind of go down a rabbit hole sometimes and you look up at the clock and you missed that time. You try to get as much preparation as you can during the week and then catch up at the end."
There has been so much positive momentum since Parker was hired in January that outside speculation has already shifted to him having too much immediate success and other teams looking to him as a future head-coaching candidate.
The Cowboys have lost only one coordinator to a head-coaching job in the last 30 years and that was Dan Quinn two years ago to Washington. Before that, you have to go all the way back to Butch Davis becoming the Miami Hurricanes head coach in 1995 and Norv Turner becoming Washington's head coach in 1994.
Parker getting head-coaching interest would be a good problem for the Cowboys, knowing it would be coming because of a very successful defense.
"What (our) talent needs is what he's bringing to the table," Jones said Tuesday on The Fan. "The right kind of communication, the right kind of tone-setting with expectation. He's got the team believing in what he's trying to do, it's something that they can execute on. He's got a great bunch, a can-do bunch."
The first step is looking like an improved bunch Sunday night against the New York Giants. Schottenheimer and Jones are confident that will happen.
"There's a difference when you can say, 'I helped build it. I helped put it together," Jones said of Parker. "Right before our eyes, I was a part of building that defense that ultimately, if you will, became a Super Bowl defense.'"
The offense is talented enough for the Cowboys to get to the playoffs. But for them to put together a deep playoff run for the first time in 30 years, Parker and his group will likely be the difference. The Cowboys are confident that their first-time defensive coordinator has the ability to make it happen.
