I must not understand false start penalties. And I mean that in all seriousness.
EDIT: Now I got what you're saying, TC. From the rulebook: "No player of offensive team may charge or move abruptly, after assuming set position, in such manner as to lead defense to believe snap has started. No player of the defensive team within one yard of the line of scrimmage may make an abrupt movement in an attempt to cause the offense to false start."
