Gutekunst's mandate already involves moving on from the AR era, whether that's sooner or later. He may fail or succeed, but I think he will be given the opportunity to do it.
Over the years, I've watched franchises do exactly what's being done here. They bring in someone as a hatchet man. Gutey is the hatchet man. His job is to usher out players like Nelson, and eventually Rodgers. He's also there to send McCarthy packing. He's the "hit man" who will eventually start the rebuilding program, but probably never be allowed to carry it through. He'll be the guy who makes a hell of a lot of money being the guy who does the dismantling. Someone will step in, replacing him, and rebuild everything from the ground up, and everyone will say it was a great idea, moving on like they did.
At times, I actually wonder if that wasn't exactly why Thompson was brought in, and the fact that Thompson grabbed Rodgers and continued team success followed, kept them both employed. Is it possible they simply overcame what was supposed to be a total rebuild?
You can disagree with this philosophy, but if you look at the history of teams, and how they were built, this is a scenario that plays out over and over. It even looks like it will play out in New England, where Kraft might have to choose between Brady and Belichek. Either way, the team falls, people are fired, cut from the team, and they start rebuilding from scratch.
I don't remember who it was who said it, but to paraphrase what they said; "Coaches are hired so they can be fired." That pretty much sums up the whole story of the NFL.
