Despite going 15-2, the Lions have plenty of holes to fill. Injuries decimated the roster’s depth and exposed weaknesses. While the decision-makers will attempt to fill most of those on the open market, several will need to be amended in the draft. Dan Campbell is one heck of a head coach, but offensive coordinator Ben Johnson and defensive coordinator Aaron Glenn could leave for promotions this offseason. If so, an even higher premium will be placed on acquiring talent to offset a potential lack of continuity in the coaching staff.
