When you allow the second-most total yards in a season in NFL history, and your team surrenders the most points in a season in league annals, there are obviously going to be wholesale changes involving your defensive unit. Such was the task for Carolina Panthers’ general manager Dan Morgan this year, and he wasted little time this offseason. There are newcomers on the defensive front (Bobby Brown III, Tershawn Wharton, and Cam Jackson), linebacker (Christian Rozeboom), and edge rusher (Patrick Jones II, Nic Scourton, and Princely Umanmielen). Defensive coordinator Ejiro Evero has plenty of new toys to play with.
