Give the Vikings some slack. If you won that many games but always got blown out when it counts, you’d do crimes too. They’re basically the NFL’s worst case of blue balls.
As a Minnesota sports fan in general, that's basically all of MN sports. We win most of the games that "matter" the least, then choke massively in the national spotlight so everyone outside MN thinks we're absolute garbage and always have been, where anyone who actually pays attention to us knows we're a good deal better than that and there's a reason we're in the spotlight in the first place. The Twins in MLB, for example, have a "historic" 18-game losing streak in the playoffs (mostly against the Yankees), but we do find a way into the playoffs more often than not. Not every MN team playoff year is some "lucky fluke", we're not always "frauds". We've been blue-balled in football, baseball and hockey for far too long.
The one exception is the Timberwolves, they just suck and always have, except for that one season in 2003.
