I can see both sides of the argument in this case. I do, however, find it interesting that we are prepared to accept head high contact in some instances but not others. You can fly for a speccy on someone's head, and if you knee them fair in the back of the head and concuss them on the way, not only will you not get pinged, you could end up with whatever prize mark of the year gets you. However, go to bump, which is still legal in our game, and therefore a 'football act', and make contact with in the head, you are considered liable for the choice you make. And I suspect most of us are happy with both of these interpretations. The issue here is that we've not seen a case of this specific nature before (spoil attempt turns into a head high airborne bump), so we've no idea where it will end up. I can see every scenario from here playing out as a possibility. I'm not even sure I know what I would like the outcome would be once I've accounted for my natural bias against Collingwood.
