Let's do a hypothetical. Close your eyes and swing your fist in the general direction of your opponent's head. If you make contact and your opponent spends a moment looking dazed, do you get a week? High, careless, low impact. (Unless you are Gaff, in which case the impact is high.)
Because that is exactly what Buddy et al have been getting fined for. They swing an elbow in the general direction of their opponent's head. If they make contact they get a fine. And I don't even understand the "careless" bit. It is not careless, but intentional. They are taking pot luck on where their elbow hits, but there is absolutely no doubt that their elbow is doing exactly what they intended it to do.
This indicates that the AFL regards this sort of head trauma as being not too bad. So if you make the mistake of laying a tackle on Buddy, Hawkins or Shuey, you've got to expect an elbow to the head every now and then.
