So just so I have this right. Contact to the head is a no no due to concussions etc. Whether its unintentional or not you get in trouble. So kicking your legs out like a ******** when you want to get up and play the ball and you make forceful contact with the head should come under the same rules. Kicking around like a fish out of water isn't necessary so this is a case whereby you could potentially remove the risk of a stray kick to the face from the game as opposed to having no chance of having your brain rattle around your head in a tackle.
