Just off the top of my head:
I’m impressed that you knew all of those players and their heights off the top of your head. 😉
I don’t particularly think it matters to my point, though, since Anya has a bigger wingspan than every single player you listed. In basketball, it really doesn’t matter very much how high the top of your head is off the ground. Height matters because it is typically a big factor in determining how high a player can get off the floor in good position to either defend or score, and Anya has that in spades. Being able to convert on offense or defense must follow, and that will come down to how dedicated he is at getting and staying in shape and working at his craft. His raw tools are better than a lot of players you listed.
