We’re counting down the top Jacksonville Jaguars free agents of the Dave Caldwell era. In at No. 7 is one of his first signings — Sen’Derrick Marks.
Sen’Derrick Marks was in the very first Jaguars free agency class under Caldwell, but he was one of the least expensive, signing one-year “prove it” contract. Originally signed to be a run stuffing defensive lineman, the team quickly realized how good he was getting into the backfield and putting pressure on the quarterback. He quickly earned a starting role and was one of the best players on the team in 2013.
