Should the Smart block on Giannis been a Defender walks under airborne shooter flagrant foul

LiveFreeFratHard Bucks11:16 pm Fri Jul 31 EDT Removed The NBA rulebook states that “Defenders may not move into the landing area of an airborne shooter. On the play in question, Giannis was attempting to dunk, and launched from just inside the free throw line. Marcus Smart moves from about 1ft inside the restricted area, and out into Giannis’ “landing area” in an attempt to draw a charge. Is there something in the rules that I’m missing that operationalizes the difference between “jump shooting” and “rim finishing” that disqualifies a dunk attempt from this rule? Is the defender not, in both cases, “walking under an airborne shooter?”
