Since Grump is back at the trainers table --- it would be interesting to hear a 5' Shanahan post on its legitimacy, And then let Kubina and other bruising blueliners study it in depth on how to deliver a legally targeted headblow. F it, they got youtube. In this season's spirit, with the best player in the world barely able to play because of concussion symptons, it's a penalty and suspendable as an illegally targeted check to the head. It's the lettered reasons you listed that Kronwall skillfully skates around being penalized and suspended, lunging not leading, from backshoulder not elbow, leaving skates after contact to finish hit, etc., apparently.
