I’m with u Steve on this one - it has always been a source of annoyance for me. They could have sideline timekeepers and every time the ref blows time out the clock could be stopped and also when a goal is scored - then they could replace the refs whistle to signal full time with a siren like in Australian football!
I like it the way it is, because the players can’t make any assumptions as to when exactly time will be up.
