Let me also ask whether the factor matches what you would see in a

game. For instance, if we calculate a player's touches per minute to

be 2 per minute, would that mean that, if he played 35 minutes, he

would touch the ball, on average, 70 distinct times in those 35

minutes?

I ask because the formula seems to not include rebounds. Obviously,

guys touch the ball when they get rebounds. If X and Y are team and

year specific, then it is possible to have a couple guys with very

different rebounding totals with similar possession factors. For

instance, Jon Barry and Ben Wallace aren't terribly different in the

main factors you list. Wallace has lower totals in all but FTA. But

he had 800 more rebounds than Barry. How do these guys stack up?

What was the original goal of the stat? Is it better to say that it

is an estimate of touches on the offensive end?
