1. Defensive end: Jared Allen retired, but the Panthers saved about $8 million toward the cap by releasing and then re-signing Charles Johnson. Kony Ealy had a monster Super Bowl, but the only other ends with game experience on the roster are Mario Addison, Wes Horton and Ryan Delaire.
2. Cornerback: Even with Josh Norman getting the franchise tag, the Panthers are razor thin at corner. Slot man Bene' Benwikere will be coming off a broken leg, and Robert McClain and Teddy Williams are the only corners under contract in 2016 with game experience.
3. Tackle: Left tackle Michael Oher and right tackle Mike Remmers held up OK, but they were liabilities in the Super Bowl. The Panthers like 2015 fourth-round pick Daryl Williams, but they need another young guy to groom.
