The Ravens defensive line is usually thought of as the deepest unit on the team. However, the late season slump in the 2016 season seems to speak against this. The Ravens mostly ran a five man rotation. Willie Henry, Carl Davis, Kapron Lewis-Moore and Bronson Kaufusi were non-factors.
Lawrence Guy is a free agent. While he provided solid, if unspectacular play for the Ravens, having a player like Calais Campbell (if he hits the market) could add first step explosiveness that the Ravens do not have on the interior.
