Football needs a 10 metre walk. At any dissent or failure to retire, the ref instantly advances the free kick by 10 metres. And if that takes it into the penalty area, too bad, tough titty.
Could be a disadvantage.
You've got a free kick 25 out, and they march you into the area. That makes it a lot easier to defend.
