If a team attempts a field goal from close range (ball placed inside 20), the setup seems to be the same as from far range, i.e. with the holder being located 7 yards behind the line of scrimmage.
I am wondering why the ball is not snapped e.g. 9 yards to reduce the chance of the kick being blocked. From close range, the extra 2 yards should not make a difference for the kicker or the center, but it would make a big difference for the defence trying to block the kick.
