You're kidding, right? So if Brady blows an ACL this (or "next"...LOL) week, you're cool walking into Super Bowl LII with Brian Hoyer? You think you'd have the same odds of winning? Wentz played at an MVP level all season and seems to be on track to be an elite QB. An elite QB is far more valuable than a wide receiver. Put Edelman on the Browns, or Jets or Jags...he's no longer a great receiver. Gronk is a bit of a different story simply because of his size, but I'd argue he's still nowhere near as valuable as Brady (they won last year w/out Gronk). Losing your star QB is far more devastating than any other position on the field. The Eagles still have plenty of great weapons, but the key one is missing.
As for no riots, fires, etc... as Cannot_Wait_4Disney outlined, yeah...they have. We Philly fans like to have fun with the "bad reputation" they have, but reality is that they aren't alone.
The cheating thing...meh. They cheated, they got caught. They aren't alone in cheating, I'm sure. There's nothing to show they're doing it this year, so I don't worry about it.
