So the Thunder are "expected" to improve based on average results for average year to year aging?
But they are currently falling short of that... maybe because they got 0.1 years younger instead of average aging?

Age and wins with only a modest correlation, you indicate.
Wonder about size of correlations for age & salary, age & playoff advancement, salary & playoff advancement, age & wins / salary...

Because everyone but Dort (and the rookies) has fallen off precipitously from last year.

At this point, almost everyone in "contest" has an estimated error less than ESPN "expert" group, except for one tie.
APBRmetrics average doing well, better than any single part.
Darko and LeBron doing very well.
( I cite Darko pretty frequently. Might "should" use it exclusively for quick takes.)

Projection by b-r.com is closer to DARKO's guess for teams on the left; closer to 'our' collective guesses on the right.
DARKO had the lowest guess on Mem, Mia, and (esp.) Mil, all of which look pretty good right now. Also highest on Tor.
For all but 3 * teams * DARKO and AvgA are on the same side -- both high or both low -- of the current projection. For those 3, any change will affect the lead.
UPDATE Nov. 9 -- 28 of 30 teams in action.

Yeah it was a rough night apparently.
I went down .44. Pelton, .67. Ncs just .27.
Several higher remain within reach. Conceivably in a night. More possible in a week. With 5 months to go.

Looks good, easy to follow. Could also take out the b-r value and simply sort them by the absolute value of the difference between the entrant's prediction and the b-r value.

Well, this way it's clear whether you wish, for example, the Knicks would do better (you do) or worse (not).
Last year I threw Pelton in with 'our' guesses, because he was the one to beat for quite a while. I could still do that with DARKO.
Sometimes a team's success will help your avg error but not help you with regard to catching the leader.
OK, best to worst, + drko:

DARKO has only a couple of best guesses for teams, but nowhere is he worst; very few are worse than avg.
His biggest error is also the best guess for Memphis.

I am tied with Darko for variances from BRef current projection by 2 or less but have 5 more of 7 or greater.
