Sammy Knight of the New Orleans Saints, said something that I agree with on the Jim Rome show today. He said if there is an injury, pretty much you can expect a fine. I think he is dead on with that.
Personally, I don't agree with the Dawkins fine, He clearly just made a good play, he was head hunting like someone else said. The league pretty soon will make all players where two flags of the same color on their hips since two hand touch will be "too violent" for them soon. Seriously they are extending the quarterback rule to pretty much all offensive positions.
The Kennedy hit was a legit fine worthy hit, as is pretty much anything Rodney Harrison does, but 75k? 50K? Thta might make them learn their lesson, but what if they weren't doing anything wrong? What does thta teach them?
