The Dallas Cowboys ushered in some significant changes to their coaching staff this offseason. It is only natural that there are some tweaks to the roster as well.

The Cowboys have a number of key players set hit the market as unrestricted free agents that they will need to bring back. According to ESPN's Todd Archer, defensive end Robert Quinn is not one of them.

They are likely to lose their 2019 sack leader, defensive end Robert Quinn, to free agency and have no idea if or when Randy Gregory can play again.

The prospect of losing Quinn to free agency would deal a crucial blow to the Cowboys pass-rushing department. He arrived in Dallas in exchange for a sixth-round pick from the Miami Dolphins and wound up finishing the 2019 NFL season with 34 tackles, 11.5 sacks, and two forced fumbles.

Although it had been a disappointing 2019 campaign for Dallas, Quinn still enjoyed quite the resurgence following a couple of down years. As a result, it is safe to assume that a veteran pass rusher of his caliber will fetch a solid payday this offseason. It seems the team does not plan on matching his price tag and will potentially look to the 2020 NFL Draft to help fill the void.

The Cowboys have a number of gaps on defense to fill if they hope to carry the same expectations going into the 2020 NFL season. They will certainly need to address their front with defensive tackles Maliek Collins and Christian Covington set to join Quinn in free agency. Meanwhile, defensive ends Michael Bennett and Kerry Hyder will also be testing the market this offseason.
