Re: Performance ratings
- Well, I'm not sure if ratings should try to measure that. That's has
always been the problem with AI; I understand the value of a guy that
can score all night long (even with low efficiency) when his
teammates can't, but somehow it seems like rewarding him for the poor
quality of his teammates.
Besides the ratings reward guys that use a lot of possesions, right?
I don't see why rewarding him even more.
In fact, I started the opposite way, tried to apply to teams the
individual ratings and it didn't work so badly. The better offensive
teams had the higher ratings and the worse had the lowests, so it
seemed like it wasn't completely useless.
I admit that I don't know what to do with the problem with assists
and offensive rebounds.

- I will agree that Manu has been gambling since about mid-season when
he moved to the bench more than he did in the beggining of the season
(in fact much more).
I actually thought he cut down on the gambling A LOT from last
season, but there was a game in New Orleans, when he came off the
bench and did it at a crucial point of the game and might have been a
huge reason the Spurs lost the game. He usually never made those
type of mistakes down the stretch of games.
Either way, I think he is generally a very solid defender. Even
though he gambles a bit these days, he still creates a lot of
turnovers via charges and steals.
And about 2001, I know Bowen was not around. But I was trying to
kind of hint towards the TWIN TOWER approach maybe being the primary
reason an SG/SF always is in the top TENDEX defensive ratings since
2001 (maybe even before that) if we were to check.
If Bowen is the reason for the SG's being held so low, then why is
the SG production PER at a net positive at +2.5? And negative at the
SF position (or was once close to it)? He certainly doesn't put up
LARGE PER and Turkoglu altough is scoring more these days and
grabbing rebounds, I would have to assume Manu, Turk, AND Bowen are
all playing solid defense. If there is any weakness in the D its
with Parker slightly, and even MORE SO at the backup PG position for
Of course the two 7 footer approach helps them all become a little
more risky etc..... But I don't see how Manu and Hedo cannot being
doing solid defensively, when the PER, defensive ratings are solid
across the board? Isn't it safe to conclude the Spurs are getting
reasonable production on both ends with the THREE MAN ROTATIOn at the
SG and SF? And the reason the SF might be low is solely because of
Bowens lack of scoring at times?
