Hmmm now i am starting to think that the game doesnt need any skill improvement add too.
it is well balanced.
BUT you said
A good rebounder will retrieve the ball more often after a missed shot. Notice that height is already considered when a player's rebounding skill is displayed. A player who is 7'2" but has a low rebounding skill simply is very bad at positioning and will not get very many rebounds
So the Rebounding skill is not just about jumping up to grab the ball. It also consists of positioning, hustling for the ball, timing of the jump, boxing out the opponent etc. So I guess speed and athleticism is somehow embedded into skills like driving.
so the height of the players doesnt affect anything???
you can have a 1.75 cm center if the his skills are all right?
If so, then it is unrealistic...
