A team-building process.
DLaw is 29, & trending downward.
Gregory, and Armstrong are free agents after the 2021 season.
Anae is a fifth-round selection from the previous defense coaching regime.
Basham signed a two-year contract as a free agent.
The Dallas defensive line is devoid of talent, and young promising game-changers.
The idea that Dallas finds blue-chipper edge rushers later in the draft -- look at these gems since 2008:
Erik Walden, Brandon Williams, Sean Lissemore, Crawford, Ben Gardner, Ken Bishop, Gregory, Ryan Russell, Tapper, Collins, Ivie, Carrell, Armstrong, Jackson, & Jelks.
Given the high significance and importance of the position, the difficulty of drafting quality edge rushers in later rounds, you grab the best edge rusher in the draft early, and you immediately upgrade not only the DL, but elevate the overall defense (in particular, the secondary) by having the one player who can single-handedly pressure, and disrupt the QB.
Don't draft by being sacred -- sacred of what might happen.
Draft the best player at the most impactful position, and thus your overall team--building improves for the future.
