I usually make two different players to fit two different needs.
I make one player that is my actual height 6'3". I try to mold him into a pass first pg that focuses on defense and has a questionable 3pt shot. (Kinda molded off rondo)
My other player is designed to dominate in the park and the rec with my friends. I make a center that is max height (height is only a positive on the park, otherwise I would probably choose 6'10 or 6'11 for story sake) which usually ends up being 7'2 or 7'3. Focus on athleticism, defense, scoring inside (alley oop finisher), rebounding and mid range spot up scoring. Again the primary goal is the park, so this doesn't really tend to be realistic. It is fun to have a world beating center on the celtics tho. I try to play within stevens system, except on my current one. They fired (or didn't resign) stevens, and hired Derek Fisher (man I hate 2k AI sometimes.)
