Sorry, I did get that slightly wrong. It's not all outfield players, just opposition ones. Once again, having been to numerous courses, I would suggest you attend some of them. Quite often when a PL official is giving a talk to a local society the public are entitled to attend but you very rarely find anyone bothered. I have said this before but football must be the only sport where the fans of the sport are ignorant of the lawsI think you're making most of that up.
It never included taking a goal kick. And if all outfield players have to be out of the penalty area before 6 seconds start, why would defenders wanting to waste time ever leave the penalty area? If it only applies once the keeper is standing, why would he ever need to get up? The 10 yard bit for attackers is nonsense.
