The Philadelphia Eagles' pass rush has been very pedestrian over the first six weeks of the season, as the Eagles have totaled just 14 sacks.

Much of that is due to the lack of production from star defensive lineman Fletcher Cox, who has surprisingly yet to register a sack this season.

But the 28-year-old is fully aware that he needs to be better:

“We’ve got to stop making excuses and just fight through it,” Cox said, according to Paul Domowitch of The Philadelphia Inquirer. “That has to start with me. I have to be better. I know I will be better. I’ve been getting better every week.”

Cox is coming off of a 2018 campaign in which he racked up 46 tackles, 10.5 sacks, a forced fumble and a fumble recovery en route to a Pro Bowl appearance and a First-Team All-Pro selection, so his lack of production is alarming.

However, Cox is far from the only problem with Philadelphia's defense, as its secondary has been maligned all season long, and the Eagles simply lack top-level talent on the rest of the unit.

Still, if Philly wants to improve defensively, it needs more from Cox.

The Yazoo City, Ms. native, who played his collegiate football at Mississippi State, was originally selected by the Eagles with the 12th overall pick of the 2012 NFL Draft.

He has made four straight Pro Bowl appearances.

Philadelphia has gone 3-3 thus far in 2019, most recently falling to the Minnesota Vikings last weekend. The Birds will take on the Dallas Cowboys in a pivotal NFC East divisional clash on Sunday.
