Jack Sanborn Brings Toughness and Leadership to the Dallas Cowboys

A Smart Addition in Free Agency The Dallas Cowboys have made waves this offseason by sticking to their strategy of finding value in free agency. While their approach has frustrated some fans eager for blockbuster signings, the team has focused on adding key pieces that fit their system. One such signing is former Chicago Bears linebacker Jack Sanborn, who brings a mix of experience, tenacity, and leadership to Big D.

Reuniting with Matt Eberflus Sanborn’s move to Dallas is more than just a fresh start—it’s a reunion. The linebacker previously played under Cowboys’ new defensive coordinator Matt Eberflus during their time in Chicago. That familiarity could be crucial in helping both Sanborn and the rest of the defense quickly adapt to the new scheme. His knowledge of Eberflus’ defensive system gives him an immediate edge in becoming an impact player for the Cowboys.

Poised for a Starting Role While some may have viewed the signing as a depth move, Sanborn has the opportunity to compete for a starting linebacker position in 2025. The Cowboys have been looking to solidify their linebacker corps, and Sanborn’s physicality and high football IQ make him a strong candidate for significant playing time. His ability to read plays, fill gaps, and contribute in pass coverage could make him a key defensive asset.

A True Team Player One of Sanborn’s most valuable traits is his leadership. He has already expressed his commitment to mentoring younger players and fostering a strong team dynamic. Speaking with DallasCowboys.com, Sanborn emphasized his willingness to be an open book for his teammates:

“I’m pretty much an open book, easy to talk to, very approachable. I’m willing to do anything to help everyone else learn,” he said. “Relatively, we kind of have a decently young room, and so just doing whatever I can with the most knowledge of the defense right now—just doing whatever I can to help guys get up to speed and just help each other out because, at the end of the day, we’re all in this together as one.”

That mindset is exactly what the Cowboys need. After reports of tension brewing in the locker room—especially between defensive stars Micah Parsons and DeMarcus Lawrence—Sanborn’s team-first attitude could be a breath of fresh air. His ability to bring players together and maintain unity will be just as valuable as his on-field contributions.

Proven Production in the NFL Sanborn has quietly put together an impressive early career, racking up 164 tackles, 4.5 sacks, 14 tackles for loss, five passes defended, and an interception over three seasons in Chicago. While he may not be a household name, his productivity speaks for itself. He plays with a chip on his shoulder, always looking to prove his worth—a mentality that aligns perfectly with the Cowboys’ blue-collar defensive identity.

What This Means for the Cowboys Sanborn’s arrival in Dallas strengthens the linebacker group while also providing invaluable leadership. His familiarity with Eberflus’ defensive scheme will help ease the transition for the entire unit, and his willingness to mentor younger players ensures a more cohesive team environment. Most importantly, he brings the toughness and work ethic that Cowboys fans love to see on the field.

While some signings go unnoticed in the grand scope of free agency, Jack Sanborn’s addition could turn out to be one of the most underrated moves of the offseason. As the 2025 season approaches, all eyes will be on the Cowboys’ defense to see if Sanborn can rise to the occasion and make a significant impact in Dallas.
