yeah exactly what he said ^
The type of offense just affects where players will look to shoot, and what positions shoot more. If you run an inside offense, your guards will drive more, so they'll need to have an okay IS rating. however, the ball should mostly be worked down to your bigs, so make sure they have a high IS rating as well. If you run an outside offense, your gaurds will shoot more. And outside offenses of course focus on outside shots so your guards should have higher JS and JR for that.
