I don't think the Eagles are for real. They run a high school offense that will be easy enough to stop when crunch time sets in. By "High School" I mean taking your most athletic player and letting him be the bulk of the offense.
Moreover, they seem to be too immature to sustain their game when opposing teams get physical with them, and their head coach is more like the schoolyard showoff with a big ego than a settled leader. Their timing is easily disrupted when they are approached by a physical defense. These intangibles may prove to be their undoing.
When opposing teams scheme to stop Jalen Hurts from sneaking out of the backfield and take away a couple of his "go-to" routes in the passing game, frustration will set in and I think they will struggle.
The may make the playoffs, but a mature coach will shut them down when the time comes. Much like Lamar Jackson struggled when defenses stopped chasing him and dared him to come to them, I think Hurts will be stopped.
Running quarterbacks are always a fad, but never a long-term solution.
That's why the NFL got away from it and the "pro-type" offensive schemes took over years ago.
