I agree ranking dunks is subjective. But though Flagg's dunk was spectacular (I'm bowing, accolades given, total respect), IMO it wasn't my greatest dunk in Duke history. Likely top 10, maybe even top 5, but not #1. I'm actually not sure what would be my #1, as I think each dunk has its own context. Athletically, the Zion dunk v. UVA was the most powerful and most impressive. He was like a tank doing ballet down the court, then windmilling it in over Huff. My gawd... GHill v. Kansas was the most meaningful being it was the early moment's of the '91 national championship, which Duke had not won yet at that time. Kansas and Ol' Roy looked at that in awe (along with the rest of us) and basically lost the game there... Henderson against Mourning and GTown in the '89 E8 was the most arrogant - "We aren't afraid of you, and we are going to win this game" dunk. Remember GTown was the #1 seed and Alonzo was a beast of a shot blocker... Dawkins doing the '86 reverse dunk, "kiss my @ss as we rout you Navy and go to the FF", was perhaps the most celebratory, closely followed by GHill (again) doing the reverse slam as the coda in that 2nd half run against Michigan in the '92 Final (time to go to bed, Fab Five kids - he should have started Curry's night-night thing then). And he was here for too short a time, but Cassius Stanley's dunk v. Miami where he flew through the lane and caught the inbound pass/alley oop one-handed and jammed it was an amazing airborne spectacle (this video below says it was #6, which IMO was way off). In fact, I think Stanley might have had the greatest dunking single season at Duke of all time (him being "only" 6'5" helps the visuals).
