I believe "legally delivers" in the rule is just that. The pitch must meet all of the requirements to make it legal. If it doesn't, then both the offense and defense gain nothing from the two infractions. I can't imagine that the rule allows us to declare a No Pitch if the pitcher stops then restarts her delivery, but grant the called strike if the pitcher leaps, crow hops, violates the 24", etc.
