Dak Prescott and CeeDee Lamb have detailed how tough it is going against Parker's defense, but what about offensive coordinator Klayton Adams?
The Dallas Cowboys defense, most think, will be vastly improved from the league-worst unit in 2025.
And yeah, the bar isn't exactly set too high to improve.
But it looks like Christian Parker and his defense are going to clear that bar with ease based on what we've seen and heard about what he's building at The Star.
We have heard CeeDee Lamb call Parker's defense "annoying" to go against. Dak Prescott had stated that it makes it tough on him, and that is two of the Cowboys' best offensive players.
So that is a glowing endorsement of what Parker is doing at this early stage of the offseason.
But what about the minds that are tasked with going against Parker on a daily basis, like offensive coordinator Klayton Adams?
How has he found going up against a defense that has so many disguises and different looks?
"It's good just because you're going to see some different things at practice that generally you're not going to see until you get into the season," Adams said. "I think that they've done a really nice job of building it the right way.
"With that family of defense, it travels well around the league because it's fundamental, they set edges, they understand their checks in coverage.
"They play splits. They coach things in coverage with very much detail, and they understand how to teach guys fundamentals and apply those to techniques."
So that is another positive response from an offensive mind going up against Parker.
Now, the true test will be in Oxnard when training camp begins, as that will be what Brian Schottenheimer calls "real football," but we can already get a feel for what Parker and his unit will be like to play against.
And it's tough.
Communication has been a big emphasis for the defense under Parker, with DeMarvion Overshown looking like he will get first crack at wearing the green dot.
When Parker was wired up for sound at practice, we could hear him tell D-Mo, "overcommunicate, overcommunicate," and we know how poorly Dallas did at that last season.
Things appear to be off to a good start for Parker's defense, and let's not forget, he's going against one of the best offenses in football, and he's making life hard.
It makes you wonder what it will look like when the NFL season begins.
