The Dallas Cowboys will square off against the Philadelphia Eagles in a pivotal NFC East matchup in Week 16. Among all of the players, Jason Witten might be the difference maker for the Cowboys versus the Eagles on Sunday.

Following the 2017 season, Witten retired from the NFL after spending 15 seasons with the Cowboys. The longtime tight end chose to hang up his cleats in favor of a microphone as he joined the “Monday Night Football” booth as a commentator. But after pondering his future, Witten decided to unretire and return to Dallas. The veteran tight end has put together a respectable season for the Cowboys with 57 receptions for 491 yards and four touchdowns.

At 37 years old, Witten is no longer able to do some of the things he was able to do earlier in his career. While that may be true, he's still shown that he can be a reliable option for Dak Prescott in the offense.

Over the years, it has been said that a tight end is a quarterback's best friend. Witten has been exactly that, as the vet has hauled in 75 percent of his targets in 2019. That is the second-highest mark of Witten's career (caught 75.8 percent of his targets in 2009).

On Sunday, the Cowboys could clinch the NFC East title by taking down the Eagles on the road. Throughout the week, it has been mentioned that Prescott is dealing with a somewhat serious shoulder injury. As a matter of fact, Prescott was unable to throw a football for the majority of the week. Nevertheless, he will be active under center when Dallas takes the field on Sunday against their division foes.

With Prescott playing hurt, the fourth-year quarterback is going to need some aid from his teammates. There's no doubt that the Cowboys are going to focus on getting Ezekiel Elliott involved on the ground early and often.

However, the Eagles own the third-best run defense in the NFL—allowing 90.4 yards per game. Provided that, the Cowboys could have to revert to the aerial attack if the rushing attack is ineffective.

Besides the rushing attack, Dallas could utilize a more short-pass oriented offense on Sunday. Therefore, we could see more of Witten and the screen-game come into fruition in Week 16. Along with the screen passes, the Cowboys will need Witten to be a reliable option in the red zone. This season, Dallas has scored a touchdown on 59.18 percent of their red-zone trips (13th in the NFL).

If Dallas wants to be crowned as the NFC East champions, they'll need another productive outing from Witten. A big-time performance in his possible last game in Philadelphia could be an early Christmas present for Witten.
