Jack Sanborn, a former Chicago Bears linebacker, has signed with the Dallas Cowboys on a promising $1.5 million deal. Draft experts like Dane Brugler had ranked him highly, indicating potential as a starter in Dallas's lineup. His experience under new defensive coordinator Matt Eberflus could lead to him winning the green dot, allowing him to relay defensive calls during games. At 6-foot-2 and 234 pounds, Sanborn aims to solidify his role in training camp and contribute to a Cowboys defense looking to improve.
