Before I dive too far into this post, I should note that I don't particularly give the referees a whole lot of blame for the Packers' loss to the Vikings.
In fact, given the abysmal standards set by NFL officiating this season, I don't even think this was that poorly of a refeereed football game. It wasn't good by any means, but good officiating is impossible to find in today's NFL. It is an unfortunate fact of life that there are going to be several outrageously terrible calls per game.
This, I believe, is not one of them.
