- I'm not sure what this is worth, but I thought the crowd might at
least be interested.
I worked up the points per shot attempt for each of the olympic
players. As a quick and dirty study, I used 0.44 for free throws,
although I'm sure it's probably a slightly different in Olympic play.
Here's what I found:
Among the top eight teams, (the eight quarterfinalists but with
Serbia instead of China) the average (through Thursday) was 1.14,
which makes it pretty easy to see the U.S.'s problem:
1.33 Duncan, T.
1.33 James, L.
1.29 Boozer, C.
1.16 Odom, L.
1.09 Marion, S.
1.03 Stoudemire, A.
1.03 Iverson, A.
1.02 Marbury, S.
0.87 Jefferson, R.
0.87 Wade, D.
0.58 Anthony, C.
0.00 Okafor, C.
By comparison, here are some of the best numbers from other teams
(min. 100 minutes)
1.47 Songaila (LTU)
1.42 Ginobili (ARG)
1.42 Stombergas (LTU)
1.41 Macijauskas (LTU)
1.38 Marconato (ITA)
1.38 Kakiouzis (GRE)
1.31 Rakocevic (SCG)
1.30 Gasol (ESP)
1.29 Garbajosa (ESP)
1.28 Yao (CHN)
--11 of the 12 Lithuania players were above the average
--Maybe it's a North America thing. Puerto Rico had the same problem
we did -- Arroyo was just at 1.10 and they had only three players
above the average.
--Carlos Delfino of Argentina was at just 0.73. I hope his D's as
good as advertised, because every stat I've seen on him says to me
he's really going to struggle offensively in the NBA.
1.08 Puerto Rico
Explains a lot. Italy will move up after the Lithuania game.

here, at least not completely. I am saying that we know that average time per possession
increased. This could have come about either by relatively fewer fast breaks in the mix -
which implies a decrease in offensive productivity, as fast breaks are "better breaks" - or
by more time spent in half-court sets - which should not imply an increase in offensive
productivity, if anything, perhaps a decrease.
You write "if the faster pace is the result of shooting earlier in half court sets [now me: this
is equivalent to going backwards in time] there is no reason offensive efficiency should
improve". This is my point exactly, going back in time, the offenses were worse.
Hence, I disagree with your last sentence. It is precisely because (in going backwards) that
the pace quickened (and despite teams presumably having the benefit of a higher
proportion of fast breaks) and their productivity dropped which implies that they were
playing sub-optimally (i.e. they could have done better than they did, just by playing more
under control and waiting for a better shot.)

basic theory and facts, we know that the game changed in a certain direction (towards
greater "efficiency"). And, we know what this means in terms of turnover and scoring
percentages, overall they increase - by "definition". Furthermore, if nothing else changed,
it is necessarily true that the fact that the game slowed during this time period implies
that things could have been done better previously, but weren't. As to other explanations,
I invite anyone to suggest them, and I have identified the categories where they are likely
to be (differing rule changes/interpretations, changes in populations, etc.) And I agree
that they should be discussed, but they need not be shown to be false for the game
improvement argument to hold. What needs to identified are the relative contributions of
various factors. (So, at the end of the day, one might say that the actual gain in offensive
efficiency from the 60s (say) to the 80s (say) was x% due to refs deciding that palming the
basketball was no longer a turnover, y% due to improved shooting ability, and z% due to
an increase in athleticism, etc.) Right now, however, I am trying to establish the ceteris
paribus argument that fast play was hasty play, causing many, many, forgone points.

because it is the plausible story. (The alternative is an odd story that the offenses were led
to their improvements by defenses playing better! This story would be that the defenses
were eliminating fast breaks and playing harder defense, obliging teams to protect the ball
more and be more patient, with great unexpected gains in productivity.) But for my
argument to play out, it depends not at all on the assumption of offenses consciously
slowing down play or being induced superior performance by better defense. (In which
instance, the superiority of the moderns versus the old school is all the greater still.)
And you are correct that improved shot selection is not neccesarily the cause of increased
productivity. But, there is no strong anecdotal evidence that players became better
shooters (and I don't think that free throw evidence would support it) so, by elimination,
that leaves shot selection (and better ball control/fewer turnovers).

increased, either there were more shots available (i.e. fewer turnovers) or they were better
shooters (but not better free throwers?) or they got better shots (call it shot selection.)
That is all possible categories, no?

shallower talent pool, etc.) Fleshing out the story of what happened and when is not proof,

average moved in one way, it will be reflected in averaged player averages. I think that the
more interesting story is to try to explain why it moved in the way it did, and my strong
prior is that league-wide strategy changes were based on emulating teams perceived as
"successful". As I have noted, my guess is that perceptions of success related (and
probably still relate) more to trying to "be like Mike, or the Celtics dynasty, or the Bad
Boys, or whatever" rather than "be like the team that maximizes offensive efficiency".
