NFL defensive line rankings: All 32 units entering the 2020 NFL season - PFF
2. Philadelphia Eagles. The Philadelphia Eagles have had one of the strongest defensive lines in football for years — not just blessed with top-end talent, but with incredible depth. That doesn’t look likely to change any time soon, and they have added multiple pieces over this past offseason. Fletcher Cox and Brandon Graham remain and are likely still the unit’s best two players, though Graham’s 2019 PFF grade and pressure total were each the lowest he’s had in a season since 2015; he may be starting to show signs of slowing down at 32 years old.
