Want to still upgrade the linebackers?
Jamie Collins (LB)
Jamie Collins is an interesting player that has been in winning culture and has two Super Bowl rings. He also had made one Pro Bowl appearance in his six-year career.
Collins was released by the Browns on March 6, 2019, and is one of the many impactful free agents still on the market. At age 29, he is coming off of a four-sack and one interception season, showing he can make plays to significantly impact a game.
Collins spent the last two full seasons with the Cleveland Browns, starting in all 22 games he has appeared in over the past two years. More specifically, Collins started at strongside (Sam) linebacker which is the only linebacker spot that is open currently for Dallas. Whether he would an immediate starter, or used for more rotational depth, he could be a player that could prove very useful for the Dallas Cowboys in the 2019 season.
