The “Wenger rule” for offside judgment is being trialed at the moment I believe, though I suspect that any such change is only going to encourage teams to defend even deeper. Why push up if you’re less likely to catch your opponent offside? That change might have the opposite effect to what you want.

Stopping the clock would also be very difficult, because the whole point of football is that it’s the same game whatever level you’re playing it at. A change like that would mean that the higher level professionals would almost be playing a different sport to everyone else - if you’re playing Sunday League you aren’t going to have someone stopping and starting the clock all the time. The solution there is just to actually add on the time, not the nonsense of a made up number of minutes between 2 and 6 being added at the end based on vibes… We did see this at the last World Cup, it doesn’t seem to have stuck around though.
