With 16 defensive linemen on the roster, it may be the Titans' deepest position. Offseason acquisitions Leger Douzable and Keyunta Dawson will provide depth. Since 2010, Dawson has played on stout defensive lines with the Colts and Lions. "Douzable came from Jacksonville -- those guys really taught stopping the run," DC Jerry Gray said. "These guys from other good programs only give you good stuff."
