Eagles News: Philadelphia has actually been the worst team in the NFL out of 12 personnel

This is why the Eagles offense is so thoroughly broken - For The Win
Despite everything I just said, though, the real reason this passing game is struggling might be because what should have been a strength has become a weakness: The two tight-end sets featuring Zach Ertz and Dallas Goedert. Here’s what I thought heading into the year: With two athletic tight ends, the Eagles would be able to confound defenses with their versatility. If a defense matched those 12 personnel (1 RB, 2 TE) sets with base defense (4 DBs), Philly would have an advantage in the passing game because either Ertz or Goedert would be matched up with a linebacker.
