Yes and the 100+ yards that the refs gave the vikes on us in penalties also did.
Edit: Oh yeah, 1000th reply.
The Vikings were the ones who ended up taking the worse of it on penalties by the end of the game, they got that pass interference on a ball that was totally uncatchable, the 12 man huddle call, and so on so penalties hurt all the way around, not just towards the Saints.
If the Vikings didn't shoot themselves in the foot so many times this game actually wouldn't have even been close, how many times did the Vikings fumble the ball and the Saints score off it, or fumble in there own red zone as there about to score, or an INT, the Saints didn't beat the Vikings, it was the Vikings that beat the Vikings. You can't say it's not right.
