Adjusted team efficiencies

I went looking for a list of adjusted team efficiencies for last season and thought I'd post this link in case anyone else wanted a reminder about where at least one version was or missed it.

Schedule does make some difference in the east and west ratings on offense and defense.

How is this calculation different from the SRS rates already shown at b-r.com?

.. I had to calculate SRS-style schedule-adjusted regular-season offensive and defensive ratings for every team since 1985-86, much like I computed in past seasons for the BBR Rankings.
The 5 best and worst teams in the interval, according to SRS; and showing also Neil's newer version:

Code: Select all

best   yr     SRS   srsN     worst   yr     SRS     srsN
Chi   1996   11.8   13.0      Dal   1993   -14.7   -14.8
Chi   1997   10.7   11.8      Cha   2012   -14.0   -15.4
Chi   1992   10.1   10.7      Den   1998   -11.7   -13.1
Bos   2008    9.3   10.2      Mia   1989   -11.1   -11.2
Bos   1986    9.1    8.8      LAC   1987   -11.0   -10.6
Last year's Bobcats are now the worst team of all time. Other recent extreme outliers are also more extreme.

I am pretty sure SRS is just MOV + SOS. It doesn't count home-away advantage, but by season's end, there shouldn't be any.

Mike G: these are now calculated based on efficiency ratings rather than on points--so it's adjusted for pace. That's the only difference.

OK, got it. Thanks. It should have been obvious, in fact.
In other words, send the 2012 Bobcats back to 1993, and playing at a higher pace, they are underdogs to the Mavs.
Assuming that their point differential is even worse in more possessions, and worse than those Mavs in equal possessions.

Well, they're just historically bad, then.
