but 7 is pretty weak, and normally the young giants aren't in the shape off the smaller one(movement accuracy(bad description but i hope that works), speed and jump Power) ...
Yeah they got also the advantage off the height, so wehen they stop grwowing and works on their feets they getting better then the small ones ... but till that times, the smaller ones will often drive around then and they throw over the heads of the small ones. So the advantage becomes part of the game through the development of the player, which ain't far away from the reality.
Normal centers wouldn't have respectable Rebound they will have profient + when you play this game longer, the same is for the other main skills.
