My first thought was a try but slowing down the slow motion on sky it looked like it flicked his fingers after it came off the boot.

I [ithink[/i that for it to count as a drop kick you have to have control of the ball with your hands at some point, however briefly. Seem to remember looking it up a few seasons ago after a similar incident. I could be remembering wrong though.

That's the Thierry Alibert rule book you're reading there.

Thought a player had to 'intend' the kick and not just boot it once he dropped it.

with some of the video referees decisions who know what ganson would of give.

If he's got his boot to the ball before it's hit the ground it's play on. If it hits the ground first it's a knock on. Intent doesn't come into it.
