The Dallas Cowboys have seen an enormous change at the linebacker position this offseason. Consider that the events of the last month, while a few predictable, have been almost a total re-shuffling of the deck in the middle of the defense. Just before the 2021 NFL Draft the Cowboys saw veteran Sean Lee retire, and then almost immediately after spent top draft picks on Micah Parsons and Jabril Cox. A few days after that they declined the fifth-year option on Leighton Vander Esch.
Obviously every move is done with the objective of improving the team as much as possible, and clearly the organization feels that moving forward with the likes of Parsons and Cox is what is best for the linebacker group as a whole.
