I agree that you shouldn't need to be told when to back-off, that should be understood by all players on the field. I do like the restrictions, however, because it's nice to have some sort of specific unified goal to be working at the time rather than just be knocking the ball around aimlessly. Can we get 9, 10, 11 consecutive passes? Can we get this crazy new combo to work? Can we take it back, switch it, and then do x, y, or z?
Captains, of course, can always set those specific goals, but a coach is another good way to make sure everyone knows and understands the particular point in time.
