Every team's fans do that. When the Panthers lose the local boards want to start overhauling the team starting with the head coach down to the ballboys. Case in point is our loss to the Giants Sunday night. You would have thought it was the end of the world and other than DW everyone got tossed under the bus. No one looked at it like this: You just played the Super Bowl champs to OT on their homefield in bad weather conditions and a hostile (It's freakin' NY) atmosphere and yes, you gave up 300 yards rushing but if Kasay is 2 ft to the left it's a win. Fans usually don't look at stuff like that.
So consider Saints fans like every other team's fans. When you win, my God, the sun is brighter, the air is cleaner and all your players should be in the Pro Bowl. When you lose... well, that bus is getting closer... I wonder if I can fit that 300 lb lineman and some of his teammates under there?
