To answer the question posed in the headline: almost everything.
The wide receiver corps hasn't broken a single tackle and are the lowest-graded unit in the NFL, their tight ends have more drops (three) than any other group in the NFL and running back Miles Sanders coughed up a fumble that put them behind the eight ball early this past Sunday.
None of those struggles compare to what we've seen from the Philadelphia Eagles franchise quarterback through two weeks, however.
Carson Wentz's 40.7% on-target pass rate is currently the lowest of any starter in the NFL, and he leads the NFL with eight turnover-worthy plays (almost one-third of the way to his 25 from a year ago) after two games. That not only means that he has been wildly inaccurate, but it also means that he's been callous in his decision-making. Unsurprisingly, he's the lowest-graded quarterback in the NFL so far this season.

So, how did an offense that was supposed to finally be healthy and back to 2017 levels go down the drain so quickly? While there's a number of issues, the biggest one is simply rapport. Call it trust, bond, feel — whatever you want — Wentz just doesn't have it with this group of wide receivers, but he has it with his tight ends, almost too much.
The confidence he has throwing to Dallas Goedert and Zach Ertz, who respectively rank first and third on the team in targets, hasn't been there with any of the Eagles' wide receivers. That doesn't excuse Wentz's dreadful performance through two weeks, but it does provide hope that things can turn around with more reps throughout the season.
