In 2015, the Bengals had one of the best defenses in football. In 2016, Cincinnati's defensive personnel will remain mostly intact. The team parted ways with Reggie Nelson, Wallace Gilberry, Emmanuel Lamur and A.J. Hawk during the offseason, and from the looks of it, Leon Hall seems more unlikely than likely to return. To compensate for their offseason losses, the Bengals added Taylor Mays and Karlos Dansby, as well as rookies William Jackson III, Nick Vigil, Andrew Billings and Clayton Fejedelem.
