if he is a C the skill sets would be inside scoring|+ rebound+ inside def+ block shot?
Correct.
and out of balance: big difference between these skills or training in a skill that the player is not suited for? (ex: rebounding for a 1m80 player)
Not really.
Let's say you have a player really good in one of his relevant skills, but the other three are lagging.
That highly-trained skill will train more slowly than it would otherwise, and everything else lags until you achieve a better balance.

A CT? Really?
Any two will do
Any three for me
Any four will score
Any five are live
