Just tweaking my primary and secondary skills for each position. I'm still not sure they are exactly where I want them... You can also look at Joseph Ka's weights in his coach Parrott program to see another idea of what is useful for each type of player. He tends not to value driving at all, which seems to be the position of many experienced managers.
My position is more that: driving does not seem to have any influence on the game ratings. However, it is most likely very useful for certain types of shots. Or maybe it just gives you higher quality shots in general, but this is not reflected in the game ratings.
