The Cowboys have a few key players hitting the market, including well-known veterans like DeMarcus Lawrence, Jourdan Lewis and Rico Dowdle. Dallas has also re-signed some playmakers, mainly defensive tackle Osa Odighizuwa. The team also still has another weapon to extend in pass rusher Micah Parsons.

However, before his injury, Greenlaw was an absolute force in the middle of a 49ers defense that was one of the top units in the NFL. Alongside Fred Warner, Greenlaw had back-to-back 120-plus tackle seasons in 2022 (127 tackles) and 2023 (120 tackles) in 30 total games, averaging 7.56 tackles per game over that stretch.

On Sunday, just a few days before free agency begins, the Cowboys made another defensive move, bringing back safety Markquese Bell on a three-year extension worth $12 million, per ESPN's Jeremy Fowler. "The Cowboys and safety Markquese Bell have agreed to terms on a three-year deal with a max value of $12M, per sources," Fowler wrote on X.
