I guess I always use individual offensive and defensive ratings, as
well as a player's percentage of the team offense. (%age of team
defense is harder to estimate, so I don't use that).
As a screen, one number gives you a sense and you can do stats on
it. I guess I like to know reasons. How can you change and predict
it? The stats from one number can help make predictions (sometimes
better than with multiple #'s because you don't rationalize a
number), but it doesn't help you _change_ anything, which is how I
like to use my stuff.
Didn't get an answer, though, to how people use each other's weights
or what they've learned from them.
