New Dallas Cowboys defensive coordinator Mike Zimmer inherits a strong unit despite upcoming free agents and cap challenges. Key defensive players like CB Stephon Gilmore, CB Jourdan Lewis, DE Dorance Armstrong, S Jayron Kearse, DE Dante Fowler Jr., DT Neville Gallimore, DT Johnathan Hankins, and CB Noah Igbinoghene face uncertain futures. Special teamers CB C.J. Goodwin and LS Trent Sieg have value to the team as well.
