I am not sure how you could come to that conclusion. The coaching did a pretty good job moving the ball up and down the field against the Saints as well as holding their offense to one of their worst performances of the year. If it weren't for all of the turnovers the Vikings could have won by 2 or 3 touchdowns. How exactly is it the coache's fault that the players can't hold on to the ball? Did Chilly forget to say, "now guys, try not to give the ball to the other team this time ok?"
I also second the idea of never having to hear about how much the city of NO needs to win the Super Bowl. There should be an expiration date on playing the "we got hit by a hurricane" card.
