More than likely he will still be a 9 point basically, that doesn't mean he may not have more mass or less, it doesn't mean he may not grow a sticker or 2 next year either. Usually if they are fully mature you will not see the "Basic" rack change drastically unless he is injured. Once they start getting beyond their prime their rack will still maintain it's basics, but will lose mass and in some cases a whole lot of mass. When they get OLD the nutrients will tend to go more to the body and less to the rack.
