Can you imagine it, yellow card given, 'but I was 11 yards away not 10'. There would be no time for spray as the kick can be taken immediately. It's all a bit of an uneccessary rule change.
Next, throw in to self? Nah it's not for me. You can just put another player to knock it an inch to the dribbler anyway as the rules currently are. What's the point in messing about with when you can and can't tackle.
