If you count national teams, Pau an Marc are just so much better than anybody. They almost beat Lebron, Kobe, Durant, etc in the olympics finals.

Is not the most important, but the most dificult to get a great player. There’s a lot less guys 7 foot than shorter guys, and the taller, the more easier to get an injury. That’s why some of them are called unicorn, because it’s extremelly rare to find a player 7 foot tall and as skilled as a good 6’4 guy. They teams that get a player like that are at an adventage over teams who struggle to get such a player.

Everybody that plays basketball uses size 7 for men and 6 for women, it is like that. Even 13 year old kids play with that sizes.
