Many people consider the Vikings to be a joke of a franchise. They should have been Super Bowl contenders when they had Randy Moss on their roster. But they fell short of greatness over and over. Mike Zimmer is probably their best coach since 2000 because they made it to the NFC Championship game (via Star Tribune).
Leslie Frazier took Minnesota to a Wild Card Game in 2012 but this was against the norm. Otherwise, the worst coach of the past couple of decades was a disaster. He departed with a cloud over his head and a .398% winning percentage. Perhaps we should say losing percentage because that’s more accurate.
