I disagree a bit. If Hurts isn't the guy, and I agree that they can win even if he's not elite, then not only are you wasting a year or two, but you also aren't a bad enough team to naturally draft a top-5 QB. So then you're looking at giving up multiple 1sts to trade up in the draft or in FA. The team did pick up a future 1st, so that does make it a little easier.
And at this point I'm not sure if we can tell if it's Hurts or the coaching. In my opinion, if you aren't sure that you have a franchise QB, then you don't have a franchise QB and will you have a lot of difficulties going deep into the playoffs.
I know I've said this before, but I'm not sure Hurts can't be elite. He was elite in HS, he transferred after a future #5 overall pick (despite his hip injury) replaced him at the #1 program at Alabama, and then he went on to be the runner-up for the Heisman only because the winner had the best college season ever.
If the Eagles think Hurts is the problem and are wrong, then it will be a much bigger rebuilding problem.
EDIT: I would describe that situation more similar to the pre-Hinkie Sixers situation than the Flyers. Picking in the mid-teens does nothing for you if you don't have a QB.
