You're missing the point though. Jumping over a guy is hard but it wasn't a necessary part of him scoring. From that situation it was expected that he would score, show-boating while he did it doesn't seem like sporting genius to me.
I mean I concede the difference between this one and the Jordan one where that spin lost the defender who looked as though he had it blocked off.
Does what I'm saying make sense? Cos this is my problem with a lot of basketball, the way the highlights I see tend to focus on stuff that doesn't really alter the game but which appears to be someone gilding the lily of a relatively easy score.
The show-boating is part of it though. It's about style as well as technique and ability.
You could also say the same of someone doing a rabona or a bicycle kick in a game of footy. It's arguably more impressive if there's an easier option and someone takes the hard one anyway and pulls it off, like scoring a panenka in a shootout.
Your criteria would rule out flair in favour of functionality.
Look at this. This isn't necessary, but it's absolutely brilliant and incredibly difficult. The guy's got a finger missing on his dominant hand too.
