Brandon, this is an example of how Rule 2 definitions can help in understanding the other parts of the rule book.
For example, Rule 6-2-6 (the rule number might be different as I only have the 2006 book with me right now) states:
"The touching of a low scrimmage kick by any player is ignored if the touching is in or behind the
expanded neutral zone. The neutral zone shall not be expanded into the end zone."
Also, look at 5-1-3f:
"The team in possession at the end of the down, if R is the first to touch a scrimmage kick while it is beyond the
expanded neutral zone, unless the penalty is accepted for a non-post-scrimmage kick foul which occurred before the kick ended."
The expanded neutral zone gives R the chance to block a low kick without risking giving up the football because they touched it.
The expanded neutral zone is used in another place, and that is in regard to an ineligible receiver down field. Can you find the specific rule? Hint, it is in Rule 7.
