You have good advice here already. 1 more quick thing to look at is height. For example, I had a 6'2 player labeled position was SF. However, he never played SF because of his height disadvantage. I always had him as my SG or at times PG. Height is very important factor in this games when it comes to how well they train at a certain skill and how they match up against others in certain positions. Anyway, don't forget to consider height as well.
