Actually, you dopn't need to worry about useage all that much with that wilt, mainly efficiency. A: He plays 48 minutes a game and b: Has over a 32.5 Useage, meaning that you can put ANY four other players with him and avoid the team penalty, although the individual overuseage penalty might apply to some of those players.
32.5 useage+ gets you 8 out of the ten points you need. THe lowest useage category (under 13.7) is .5 points. So you get four players at .5 points plus wilt's 8 and you have ten.
