I disagree with the saying that driving isn't that important. If you have a dynamic big guy they won't shoot as much without higher driving. I've had 100k centers that were much better than the competition that had average or less driving and wouldn't shoot. My offensive flow was good enough to get them the ball but they wouldn't ever shoot. If had to say what skills to go for.... the obvious ones IS, ID, REB, then, JS, DR, JR, PA, OD, HN. It also depends on what you're looking for how your team is built, what offense you like to run. etc.
