In Part 2 of a two-part Inside the Birds series examining the Eagles' roster headed into the offseason, Eagles Insiders Adam Caplan and Geoff Mosher  go through the defensive side of the roster, looking at potential departures, areas in need of upgrade and the team's thinking in getting younger and more dynamic. Caplan also dishes intel on the Eagles'  coaching staff vacancies and other chatter he picked up from his time at the East-West Shrine Bowl practices.
