FALSE STARTS
Rule 7-1-7 is clear as to what constitutes a false start. A false start occurs if a player commits
a shift or feigned charge simulating action at the snap, if any player’s act is clearly
intended to cause the defender(s) to encroach, or when any offensive player(s) on the line
between the snapper and the player on the end of the line, after placing his or her hand(s)
on or near the ground, moves his or her hand(s) or makes any quick movement. This last
statement is referring to that final set position prior to the snap that is assumed without a
previous shift occurring or after a previous shift has occurred.

Taking this rule to say a QB varying his cadence is a false start is frankly completely insane.
