Even though they haven't been recording a lot of sacks so far this season, the Eagles defensive line has been one of the team's biggest impacts this season. Pro Football Focushas pass-rush grades for every team, and through the first six weeks of the season, the Eagles come in at #1 with the highest grade in the NFL.
When looking at their grades, Pro Football Focus also measures teams' pressure percentages. This is significant because it shows that the team is 1st overall at total pressure, but they are ranked 25th overall when they try to pressure the quarterback by blitzing. This shows just how linemen like Fletcher Cox, Brandon Graham and Michael Bennett are able to pressure the quarterback all by themselves. If they continue putting pressure on quarterbacks without blitzing, that will be helpful for the secondary to try to focus more on pass coverage.
Things could change as the rest of the season progresses, but right now the Eagles defensive line is the best in the NFL.
