As the Dallas Cowboys have put together this 2019 team, they have a mix of constants and variables that will hopefully produce a winner. Today, we’re going to look at those x-factors; the players or other circumstances who have a wide range for potential impact. How could these potentially swing the results for this season?

Constants are guys like Zack Martin, DeMarcus Lawrence, and Ezekiel Elliott. If they’re on the field then they’re some of the best at what they do. I also believe that we’ll continue to get Pro Bowl play from the likes of Dak Prescott, Byron Jones, Leighton Vander Esch, and other studs from last season.

As for the x-factors, the biggest every year, for every team, is health. One bad injury can take a 12-4 contender down to a 4-12 weakling, as the Cowboys experienced in 2015.

We’re not talking about health issues or suspensions today. Assuming all of our projected players are present and playing, whose impact on the field could create the biggest swing from 2018 to this season?

Our list contains two new additions from free agency who could cause some big ripples. There are also two returning players whose continued development could work wonders. And then there’s also a change in Dallas’ coaching staff, which you likely have just guessed, that could have the biggest impact of all.

In fact, let’s start there.

Kellen Moore, Offensive Coordinator

Will the Cowboys’ change at OC lead to a more explosive, less predictable offense? They must think so, having handed the job to Moore despite his having only one year of experience in a coaching role.

Scott Linehan’s run was far from bad. Over his five seasons the Cowboys won three division titles and two playoff games. The only losing season was when they lost Tony Romo in 2015 and didn’t have a Dak Prescott to replace him.

But Linehan’s tenure was also marked by an offense that every armchair coach in Cowboys Nation could predict. There was little razzle and even less dazzle; Dallas ground out wins on the strength of the run game and offensive line.

The old school approach works up to a point, as we’ve seen with four winning seasons out of the last five, but is it really the best way to go? The fact that all four teams in conference title games last year, Kansas City, Los Angeles, New England, and New Orleans, have more modern-styled offenses should tell you something.

It seemed to tell the Cowboys something, leading to the switch from Linehan to Moore. Will Kellen get more creative with the versatile skills that Dak Prescott and Ezekiel Elliott offer? Will he actually throw some passes to a fullback with receiving ability like Jamize Olawale? What about gimmick players like Tavon Austin or rookie Tony Pollard?

If Moore is the real deal as an offensive guru, this Dallas offense could do some special stuff in 2019. It would be the biggest personnel change of the offseason, on or off the field.

DE Robert Quinn

It’s been a long time since Dallas had two true studs at defensive end; DeMarcus Ware and Anthony Spencer were the last pair that could consistently threaten from both sides. By signing veteran Robert Quinn to be DeMarcus Lawrence’s new wingman, the Cowboys are hoping to restore that dynamic.

Still just 29 years old, Quinn should have plenty offer. He’s been a double-digit sack man three times in his career and has averaged 7.5 sacks over the last two seasons.

Last year, Dallas got solid play from Tyrone Crawford and Randy Gregory at times but they weren’t consistent enough. Quinn not only bring a greater track record for pass rushing, but he doesn’t present any of the current problems that Crawford or Gregory have with legal issues and/or possible suspensions.

That said, Quinn does have plenty of  NFL mileage at this point. He has shown some decline the last few years, and if that continues then he may not make the impact we’re hoping for. In that case, Dallas pass rush may look the same as it has the last few years.

Lawrence has been great, but we saw the Cowboys’ inability to get to Jared Goff in their playoff loss to the Rams. There were zero sacks that day for Dallas, and only one QB hit (Jaylon Smith) the entire game.

If the Cowboys want to get back to the NFC Title game then they need more. Hopefully Robert Quinn can bring it.

WR Randall Cobb

As I said before, Amari Cooper should be as good as ever now that he gets an offseason to work with the team. Michael Gallup’s progress from a strong rookie season is already reportedly on point. That leaves Cobb, the free agent replacement for Cole Beasley, as a major x-factor on offense.

Losing Beasley has the potential to hurt this team far more than we want to admit. He was Dak Prescott’s security blanket for three years; his favorite receiver when the going got tough. No player was more trusted to get open, make the catch, and fight for the needed yards.

That sort of pressure won’t be put all on Randall Cobb’s shoulders. Cooper and Gallup will be a better pair to work with than any Beasley ever had. They will help mitigate the risk that Cobb has lingering injury issues, or doesn’t acclimate quickly to his new offense.

But as the Cowboys hopefully shift to a more modern and innovative offense, Cobb brings valuable experience from his time with the Packers. He was part of six playoffs teams, and made many key plays to help Green Bay have sustained success during most of his time there.

If healthy, Cobb has the skills to replace Cole Beasley and perhaps even eclipse him. He was once a 1,200-yard receiver as the second option behind Jordy Nelson.

If he still has that gear in him, the combination of Cobb, Cooper and Gallup may give Dallas the most dangerous trio of receivers it’s seen in decades.

CB Chidobe Awuzie

Switching Byron Jones back to CB last year proved a strong move, helping Dallas get to the playoffs and getting Jones to his first Pro Bowl. The Cowboys are hoping that Awuzie, entering his third season, will emerge as another standout performer at cornerback.

Awuzie, the Cowboys’ second-round pick in 2017, had a slow start in his sophomore year but improved as the season went along. He should compete with Anthony Brown for the starting job, and at the least be Dallas’ nickel CB this season.

With the Saints, Packers, Patriots, and Rams all on the 2019 schedule, plus two games with the Eagles, the Cowboys need a solid secondary. They need to make opposing QBs think twice about which side of the field they want to try and throw to.

Awuzie has flashed his potential these first two seasons, but now it’s time to keep it on full display. Year Three is when most guys, and especially one taken in the second round, should be blossoming into the players they’re going to be for the long haul.

If Chidobe takes that next big step forward then Dallas’ defense could be the best in the league. The compound effect of improved coverage and a stronger pass rush would have exponential benefits.

TE Blake Jarwin

If Jarwin can do anything close to his Week 17 performance over the course of an entire year, he’d be one of the top tight ends in the game. That’s the excitement level some have around the assumed 2019 starter.

Blake’s not going to have those kind games often. The Giants were barely playing in that finale, likely already focused on how to screw up their draft. But it did give us our first full taste of Jarwin’s receiving skills and athletic potential.

The Cowboys and Jason Witten swear that the returning legend is only here to support and help, and that the majority of snaps will still go to the young talent. If Jarwin can build on last year, and learn some things from one of the all-time greats, he could be a major new weapon in the 2019 offense.

Also helping could be the switch Kellen Moore as coordinator, who will hopefully find more creative ways to utilize all players. Perhaps we’ll see Jarwin line up in spots that Scott Linehan never thought of, or was just never able to use while he still had Jason Witten in his twilight years.

Whether it’s Jarwin or Dalton Schultz, Dallas will hopefully get some more firepower out of the TE position this year. As teams hopefully focus on stopping guys like Amari Cooper and Ezekiel Elliott, we could see huge plays by the tight ends if they’re able to take advantage.
