As I understand it you get to choose which of the 4 position archetypes to spend your skill point on , and the game adds randomly to that archetypes pertinent attributes to raise your overall 1pt
Presumably the 1pt overall rise in one archetype calculated overall may also increase you in other archetypes if the attributes overlap, which I'm guessing they must
Regardless you can choose any of the archetypes to improve, not just the one preferred by your team scheme , could have read that wrong though
