well, a possession is supposed to go:
usg% - who ends the possession?
shoot a fg or turn the ball over
if shooting, is it a 2 or a 3?
did the person get fouled while shooting?
There should be some factor that decreases the chance of a foul occurring if it's a 3. There should be an increased chance of a foul if the shot is in the paint. That'd help make guys that lived at the line (like Dantley, West, Barkley, Mailman) more valuable in the current sim, and maybe we'd quit seeing Ray Allen have as many or more ftas than Wilt Chamberlain.
