So says the Ringer.com:

With Fletcher Cox on the inside and Brandon Graham rushing off the edge, the Eagles feature one of the most unblockable pass-rushing duos in the league. But defensive coordinator Jim Schwartz’s pass-rush rotation is as deep as it is talented. A league-high seven guys registered 20-plus pressures on the year, with Cox (50 pressures, and Graham (60) bolstered by Chris Long (above, 51), Vinny Curry (47), Derek Barnett (37), Timmy Jernigan (23), and Beau Allen (21). Schwartz keeps his defensive front fresh all game by constantly shuffling the lines—Cox has played a bunch of snaps the past few games, but Graham led the team’s defensive linemen in snaps this year (663), just 64 percent of Philadelphia’s defensive total. Fatigue becomes a real issue for opposing offensive linemen, who typically play every single snap when healthy; that freshness factor manifested into a league-high 40.8 pressure rate for the Eagles defense this year, with 287 pressures, 19 more than the second-place Jaguars.

Cox is the straw that stirs the drink from the inside, and he’s probably the best interior lineman in the NFL not named Aaron Donald. He mixes a rare blend of first-step quickness to get up the field and into the pocket …

… with the power to play on the nose and bull-rush straight through opposing centers and guards:
