Quite right. Thing to remember is what the offside law was introduced for.
It was brought in to prevent what we used to call ‘goal hanging‘. It was not introduced to try see if a bloke with size 11 feet is marginally closer to the goal that the bloke with size 6’s!
Have never understood why they don’t just say, if ANY part of an attacker is onside, it’s onside. It’d clear all this nonsense up once and for all and would help the assistant referees no end.
Finally, to people who say ‘they’re the rules’, so is the rule saying the keeper should be behind the line until the kick is taken, which was undoubtedly ignored in that shoot out.
