Eagles should make 3 defensive changes now that Jonathan Gannon is returning - NJ.com
Replenish the defensive end position to provide a better pass rush. The Eagles sack numbers changed dramatically after former defensive coordinator Jim Schwartz left and Gannon took over the defense. The Eagles finished next to last in the league in sacks (29). The Eagles had hoped that Derek Barnett would be disruptive off the edge. However, Barnett was inconsistent and committed several questionable penalties. The Eagles also brought in veteran Ryan Kerrigan to act in a Chris Long-type role, playing as a pass-rushing specialist while mentoring younger defensive linemen.
