They have not, however, added any pieces to help the pass rush.
The Eagles recorded 37 sacks in 2013, which ranked 20th in the NFL. Trent Cole led the team with eight sacks. Connor Barwin had five and three players -- DeMeco Ryans, Mychal Kendricks and Vinny Curry -- had four apiece.
"It's hard to find pass rushers, especially on the open market," Eagles general manager Howie Roseman said in this Philadelphia Daily News story. "There aren't a lot of teams letting them go. And then you look at the draft and where those guys go, they go high.
"Certainly, you want to continue to add pass rushers. But we feel we have some guys we think can rush the passer and fit what we're doing at the outside linebacker position."
Philadelphia had interest in DeMarcus Ware, and the Cowboys were not keen on possibly seeing their all-time leader in sacks twice a year, but the Denver Broncos swooped in with an offer Ware could not refuse ($20 million guaranteed).
As the Eagles move into their second year in the 3-4 scheme, they will have a better feel for what they want in an outside linebacker. Projecting a college defensive end to outside linebacker in a 3-4 is never easy, but it is something the Pittsburgh Steelers have excelled at for years.
