Actually, this was interesting to look at for me because it shows the
minutes distributions 82games is using, which I've always wondered
about. Obviously, the key to using any kind of P-Diff methodology is
the underlying assumption that we the matchups are correct.
I bring it up b/c there's a couple cases in the chart where this is
clearly incorrect -- Earl Boykins playing nearly half his minutes at
off guard, for instance, or Zoran Planinic having 0 minutes at point -
- with obvious ramifications for the value of their P-Diff numbers.
Another conundrum is teams like Denver and Indiana who seem intent on
confusing us because they insist on calling Marcus Camby and Jeff
Foster their "center" even though Nene and Jermaine O'Neal spent the
whole game matched up against the opposing center.
I don't mean this as a knock on Roland & Co. -- putting that together
was a monumental task and they deserve our thanks for it -- but it
warrants mentioning that we have to get the matchups part right, or
our resulting data isn't reflecting reality.
