... and underachievers.
Of players active last season, 73 had at least 1500 career playoff minutes.
Relative to their regular season productivity, top and bottom 30 in career estimated 'extra' points created, per 36 playoff minutes, on offense and defense combined:

p/r2 is a playoff to regular-season productivity ratio, with production scaled to team and opponent averages.
A p/r2 of .9277 yields a net of zero overachievment over 275 current players with playoff experience, thus is modern NBA avg. Totals are adjusted to this avg, in other words.
Minute totals are subject to small rounding errors.

Is the data r-p or do you mean p-r?

Do you have the offense and defense broken out separately? I assume the defense does not rate individual shot defense or overall individual defense but rather implicitly uses some overall team shot defense numbers for all plays even when player is not on court?

Thanks, it is indeed P-R (playoff minus regularseason)
Any surprises in these lists?

The only 'defense' included is to factor in opponent points and rebounds per game.
So, if you averaged 15 pts/36 in both the season and the playoffs; but you held opponents to fewer PPG in playoffs; that is seen to be an improvement in your scoring rate. And this boosts your 'standardized' productivity (all else being equal).

I always mean to get something like this out at the end of the season, in anticipation of playoffs. One could regress these to the mean, put in an age factor, etc. But I never have time at that time of year.
Meanwhile, these numbers will have the same validity in April as they have now. Maybe someone will remember and revive the thread.

So last season about 15% overachieved by 1 or more pts on this metric and the same for underachieving by 1 pt or more.

For career about 16 of the highest overachievers won titles. About 11 of the biggest underachievers did as well. Not that big a difference. Of course I can't see the title season in isolation from the career stats.

^^ These are career rates, of players who were active in 2013-14.
Durant on the minus side was surprising to me. Here in a nutshell are his annual RS-PO changes in shooting% and various production rates (ratio RS/PO)

Code: Select all

year    Min     eff%    Sco     Reb     Ast     T
2010    231    -.105    .78    1.00    1.08    .79
2011    724    -.005    .90    1.05     .94    .93
2012    839     .022    .99     .87     .96    .93
2013    485    -.069    .94     .97    1.10   1.05
2014    815    -.061    .72    1.07     .68    .76
A disappointing first playoff appearance, but in short minutes; then 2 average runs and an exceptional one -- all relative to his regular season that year -- and this spring, a fairly terrible postseason, relative to his alltime-spectacular season.

Before the 2014 playoffs, his career po/rs was .943 -- above the norm of .927 and decent for a superstar. Now it's .893, and he's already breaking down.

I'd expect to see more disparity in East and West po/rs. With tougher matchups, the West players should have bigger dropoffs in the postseason. But I don't see a preponderance on either side.
