Probably closer to 15 mins each half, but if the ref stopped his watch you may be right it could take even longer as players wouldn't need to "hurry" up at all.
It would probably even itself out - sides a goal down tend to rush to take corners throw ins etc. Sides a goal up tend to take an age to take them if there is no benefit it will be more like the time players take early in games when there is no great urgency
If you are referring to the International Board ruling about players circumventing Law 12 regarding an intentional pass to the Goalkeeper I think you will find that that covers unnatural methods of avoiding the the ball being intentionally passed back i.e kneeling down to knee or head the ball or flicking it up to head or chest it back then yes I would agree with you. However as I interpret the change to Law 13 and 16 the ball is in play the moment it is touched and it does not detail how the ball should be played other than kicked. Also if opposition players are not allowed in the area at goal kicks and defenders are, there is nothing to stop the Goalkeeper playing the ball to a defender at waist height or above to a defender who heads or chests it back or the keeper to pick up, that is not an unnatural action. Therefore no offense has been committed! Knowing how professional teams are these days it will not take them long to work out and practice this at the end of games to run the clock down, I suspect an IBR next season to close the loophole. It will be interesting to see how the PGMOL national conference interpret this area if at all. Good talking point Dabber ex PGMOL elite level official
I think I once read somewhere that the reason the clock isn’t stopped every time play stops, like throw ins etc. is that the results would take ages to “trickle “ in as the games lengths would be dramatically different. Thus messing up TV schedules
i seem to remember gary mabbut getting a yellow for getting on all 4's to "head" the ball back to the 'keeper just as the rule had come in, but old age and poverty may have confused me
I remember Brian Laws doing the same thing, for Forest, in a Charity Shield match,which was possibly the first game in England where that rule was introduced.
That's a possibility. Like to see them try it at oakwell with moore and woodrow breathing down the defenders neck though
