CAROLINA PANTHERS (11-6)

UNRESTRICTED FREE AGENTS: Gs Andrew Norwell and Amini Silatolu; DEs Julius Peppers and Charles Johnson; DT Star Lotulelei; QB Derek Anderson; TE Ed Dickson Ted Ginn Jr Jersey , Ss Jairus Byrd and Kurt Coleman; CB Teddy Williams; LB Andrew Gachkar; WR Brenton Bersin; RB Jonathan Stewart.

RESTRICTED FREE AGENTS: TE Scott Simonson; G David Yankey; WR Kaelin Clay; CB LaDarius Gunter.

NEEDS: Panthers need thumper at safety after releasing Coleman, as well as pass rushing defensive ends after release of Johnson and with 37-year-old Peppers' future uncertain. Team allowed All-Pro guard Norwell to walk, but believes last year's draft pick Taylor Moton can step into that spot. Center Ryan Kalil and outside linebacker Thomas Davis said they will retire after season Otis Sistrunk Jersey , so it's time to address those areas. Carolina cut Stewart, its all-time leading rusher; team needs complement to Christian McCaffrey in backfield. Finding speedy wide receiver remains priority. Don't be surprised if Carolina drafts quarterback at some point and parts with Anderson.

AVAILABLE SALARY CAP SPACE (approximately): $24 million.
