Phoenix, Ariz. — If there was an obvious roster concern the Detroit Lions have yet to upgrade this offseason, it's been at defensive tackle.
The team was proactive in re-signing its own free agents, namely Isaiah Buggs and John Cominsky, who splits his time between edge and interior alignments, but haven't made any additions to a group that had modest success rushing the passer and played a key role in allowing opponents to average 5.2 yards per carry. But, with plenty of cap space remaining, the team is continuing to explore options on the market, including six-time Pro Bowler Calais Campbell.
