presume that all defense is played by the shooter's defender.
It'd be interesting to find out how Carlisle's ass't coaches
or scouts or whoever it was who did the video work computed
Artest's defensive stats. The article makes it clear that
they were viewing video; were they allocating defensive stops
to just one player or did they have the freedom to allocate
them to multiple players? Ditto for made shots.

Isn't it often hard to classify what position a player really plays (let
alone the position he defends)?
Don't get me wrong - the PER differential can give SOME insight. But we
need to remember the limitations.
I can promise you that Reggie Miller's low opposing SG PER can be greatly
attributed to Ron Artest (and maybe a few others). That's the type of thing
I'm talking about.
