Apparently, nobody is aware that MIN offered both Darnold and Jones contracts which they both chose to leave to pursue elsewhere.
And no one is aware that SEA probably has the best defense in the entire league, which seriously covers up Darnold's bad games, which statistically have been most of his recent games before today's. Lots of lots of games with, like, 150-200 yards and a single TD or less, all ending in wins anyway.
Sometimes, you just have to accept that the fit wasn't right, and now they found better ones. That does not mean that same success would've happened for MIN otherwise. As for GM and HC, fire and replace if you want. Just make sure to sell off the entire roster and start over with that. The roster now is built around JJM and some cheaper-ish free agents in order to pay for Jefferson and the tackles. You don't have time on those to spend another 2-3 seasons drafting in while still finishing in the middle of the pack every season (which is mainly why KOC has kept his seat cool to begin with -- they still win games).
