The rules require that the defenders allow 10 yards 360 degrees around the ball. There is a difference between purposely standing 2 feet from the ball to prevent a quick restart and trying to get 10 yards away but missjudgeing by a couple of yards. I agree with arrgy, when I was refereeing, I cautioned players who stepped within two or three yards of the ball in a blatant attempt to prevent a quick restart which the attacking team has the right to take.
