You are comparing apples to oranges. Here, why the underlying fault is with the referees, the Vikings are claiming the Saints knowingly broke the rules challenging the ref to call the fouls throughout the game. it was done as a means of intimidation. In our case, I do not know if the Rams defender was purposely committing a foul or that he mistimed the arrival of the ball and was trying to prevent the catch. I honestly think the latter. This is the exact opposite what the Vikings fans are claiming. If the Vikings fans said we lost due to crappy calls, we can chimed back, welcome to our world.
Saints misfortune goes well beyond that one year. You can characterized all our missed opportunities due to poor execution at the end of games. I think quite of few Saints fans would admit to that. The vikings fans do not mentioned the turnovers, but rather dirty play.
