I am just going to throw this out there for thought:
Whether you feel (as I do) that the refs are slightly in the tank for Dallas or not is not relevant. Detroit has a team with a dirty reputation and a player who should have been watching the game on his couch for trampling someone. The reputation is long earned and well deserved. When you act that way on the field and have that kind of rep, the refs are NEVER going to give you the benefit of the doubt, especially with the attitude they have about it whenever Suh does something assinine. In fact, they are going to be watching you a lot closer. And they set the tone for this game with some of the early cheap shots on Beasley and the kicker. Perhaps if Detroit was not pull wonky shit all the time they would be cut some breaks from the refs. Of course they could also have avoided all of this by not completely collapsing in the second half, especially against a secondary where they had CJ and Taint running routes all day.
