you want lower usage... higher usage means he's more likely to end up shooting the ball, getting fouled or turn it over.
I won't do Kidd on a low rebounding team because I want my team also be a winner. Also, I want to get Wilt to do it. I got him really, really close once (needed 31 assists and everyone in my division played H/C or SD on me in the last 10 games for some reason).
