The NFC East was one of the weakest divisions in the NFL during the 2019 season. Despite all of their injuries, the Philadelphia Eagles won the division with a mere 9-7 record.

After a poor showing from the NFC East, all four teams are expected to be active in free agency this offseason. Of course, the Washington Redskins are entering a new regime with Ron Rivera being hired as their next head coach.

Similar to the Redskins, the New York Giants are beginning a new era with Joe Judge replacing Pat Shurmur. Both the Redskins and Giants figure to have eventful offseasons in hopes to compete for the division title in 2020.

On the other hand, the Dallas Cowboys and the Eagles need to bolster teams that are already littered with talent. All that being said, here is the one player that every NFC East team needs to sign in NFL free agency.

Dallas Cowboys — Dak Prescott

Since last offseason, Dak Prescott has been longing to get a long-term deal done with the Cowboys. While Prescott was patiently waiting to get a deal in place, Carson Wentz and Jared Goff received lucrative extension with their respective teams.

Rather than accept an offer that puts him below those two in terms of salary, Prescott bet on himself in 2019. Following a career year from the former fourth-round pick, it's safe to say he made the right choice.

Even amid the dysfunction occurring in Dallas throughout the season, Prescott proceeded to throw for a career-high 4,902 yards, 30 touchdowns, and 11 interceptions. Besides Prescott, the Cowboys also have Amari Cooper to worry about in free agency.

But without a doubt, the Cowboys need to prioritize keeping Prescott under center for the foreseeable future. Whether it is by way of the franchise tag or a multi-year contract, Jerry Jones needs to get a deal done with Prescott this offseason.

New York Giants — Byron Jones

The Giants were among the shortlist of teams to hire a new head coach this offseason. After failing to lure Matt Rhule from Baylor, New York chose to hire Judge. In Judge's first offseason, it's vital for the Giants to shore up the secondary.

After releasing Janoris Jenkins near the end of the 2019 season, New York deployed four cornerbacks that were either in their first or second season in the NFL. Due to the inexperience at cornerback, the Giants should be targeting Byron Jones.

With the Cowboys needing to keep Prescott and Cooper, Jones appears to be the odd-man-out this offseason. Since making the move to cornerback in 2018, Jones has evolved into one of the league's best shutdown cornerbacks.

The Giants, who play the Cowboys twice a year, can attest to how talented Jones is. Signing the former first-round pick would give New York some assurance in their secondary.

Philadelphia Eagles — Chris Harris Jr.

Similar to the Giants, the Philadelphia Eagles are another team that could be in the market for a cornerback this offseason. Once free agency begins, both Ronald Darby and Jalen Mills are slated to be unrestricted free agents.

While the Eagles are fond of Mills, it's likely that Darby heads elsewhere this offseason. Throughout the 2019 season, it was apparent that Philadelphia could benefit from adding a proven cornerback to the defense. Going back to last year, Chris Harris Jr. has been someone that has been on the Eagles' radar.

In recent years, the Eagles have made a concerted effort to add veterans that can be a key contributor to the team. Harris, a four-time Pro Bowler, is a player that would be perfect for Philadelphia's locker room. Also, Harris' ability to excel in the slot or on the outside is a valuable asset.

Washington Redskins — Brandon Scherff

As previously mentioned, the Redskins are beginning anew with Rivera manning the ship next season. With a second-year quarterback and Rivera trying to rebuild the roster, the last thing Washington can afford is to break apart their offensive line.

Last week, the Redskins finally gave permission to Trent Williams to seek a trade. Williams sat out the entire 2019 season due to a medical dispute with the team and is eager to get a long-term contract that rivals the highest-paid left tackles in the NFL.

With Washington heading toward a divorce with Williams, they can't allow Brandon Scherff to leave in free agency as well. Scherff has been a vital piece of the offensive line since 2015, making a Pro Bowl in three of his five seasons.

If the Redskins aren't able to get a new contract completed, then their best option is to franchise tag Scherff. Regardless of how they get it done, retaining Scherff is essential to the future of the organization.
