No. 1 former Jaguars player who remains unsigned: Myles Jack, linebacker
Linebacker Myles Jack seemed like a good bet to go in the first round of the 2016 draft after a highly productive career at UCLA. However, a knee injury made him tumble down to the second round, where the Jags picked him at No. 36.
Jack would go on to become a mainstay of the Jaguars' defense and was one of their few players that earned a second contract. Although he didn't get any mainstream awards for his contributions to Jacksonville, he proved to be reliable, tallying 513 total tackles, two forced fumbles, and three interceptions. Moreover, he was named team captain three times during his six-year stint in Jacksonville.
But all good things must come to an end and the Jags released Jack last offseason to free up $8.4 million in cap space. They then used most of the savings to sign Foyesade Oluokun while Jack signed a two-year deal worth $16 million with the Pittsburgh Steelers.
In retrospect, moving on from Jack wasn't an easy decision, as he was a core contributor throughout the late 2010s. However, his chronic knee injury claimed some of his athleticism in recent years and Olukon has proven to be a solid replacement if not an upgrade. Also, Jack has already been released by the Steelers, so it's fair to say that the Jags made the right call.
Make no mistake though, Jack always gave 100 percent effort, even if that didn't translate into wins and his contributions as a member of the Jaguars will always be remembered.
