You are kind, but that was a major gaffe.
It will be very interesting to watch what happens with the Eagles this off-season, especially if, as I strongly expect, they exit the playoffs after one game. For one thing, we likely will learn something about who has been playing through significant injury, if only from reports of off-season surgeries.
Lurie clearly won't fire himself and Roseman appears safe as his alter ego. That means the onus and change will fall upon Sirianni, his staff, and the players. I think Siiranni is safe, but there should be a lot of thinking about the change in Defensive Coordinator, with not much accompanying change in either who plays how much or what plays are called and certainly zero sign of improvement. It seems like a panic move which drove dismay and chaos in the ranks without addressing the actual problems of the defensive scheme. There will be changes in the defenders on the roster: decent LBs please and a safety, Cox and Graham are just too expensive for what they are. There need to be changes in the defensive scheme. I've watched how much the Eagles offense is destroyed by varied blitzes. Surely someone with some authority has noticed the same and possibly got an inkling that blitzing more might well improve the D. Our D has problems with quick-hitting motion plays. That might suggest to a wise person with some influence over O that more motion and less RPO might help the team.
My predictions: Sirianni and Roseman stay
Desai and Patricia are gone
Johnson is gone or returned to a role like QB coach where he can work with Hurts
No change on ST coaching.
Stoutland has the job as long as he wants it but other position coaches depend on wishes of new coordinators and the scheme changes upper execs want to see. I think half of O and D position coaches will be replaced.
In draft and FA treat this as rebuild-on-the-fly. Emphasis to add: DE, DT, LB, S, CB, OG, cheap RB
Do or die year for Sirianni. Sirianni more involved in offense. Shorter leash on Hurts.
