[Not really racist!]

Kronwall actually takes a stride forward before nailing him IIRC, fuck I hate that hit every time I re watch it. Usually Kronwall executes that hit with his back towards the player, but I guess in this case the shoulder of Kronwall got him nice and square. Doesn't Rule 48.1 have some leeway as to the player delivering the hit having to hold up the hit if they know it'll turn ugly?

48.1 Illegal Check to the Head– "A hit resulting in contact with an opponent's head where the head is targeted and the principal point of contact is not permitted. However, in determining whether such a hit should have been permitted, the circumstances of the hit, including whether the opponent put himself in a vulnerable position immediately prior to or simultaneously with the hit or the head contact on an otherwise legal body check was avoidable, can be considered."

That's all it says.. and does mention the vulnerable position part.
