I've seen much debate on the short kick off and the TV made it seem like a ridiculous decision but I'm not sure of the rules?
My understanding is that the ball must travel 10m forward but I don't think this includes the position of the receiving player's feet. That is, if the player's feet are beyond 10m but the ball isn't, then the ball has still not travelled the required distance.
The ball was in the air and the touchy directly in line with the 10m so should've clearly seen if the ball had travelled far enough.
