2025-26 team win projection contest

Post by Crow »

Enter to be "officially in", if interested, fwiw.

Don't enter, you might still be tracked or can score yourself.

Average difference of almost 3.5.
50% more difference in west.

Pelton closer to 41 only about half the time.
But only higher than EBET twice when EBET was over 45.

Every year I neglect or forget to put an age correction in my predictions. We all know that younger players tend to be better this year than they were last year, while older guys are likely to have declined. Right?

I gathered up 10 years of my own non-age-curved team win predictions and how they varied from actual Wins -- correcting for the Covid-shortened seasons (2020 and 2021) and attempted to find a formula that incorporates avg team age and reduces my errors.

After many attempts, it's clear there is a positive correlation with age: Older teams have tended to out-perform expectations, while younger teams have underachieved. Sorting by age and dividing 360 team-seasons into thirds (120 each) the averages are:

Code: Select all

age	pred	actW	err
28.3	46.4	47.4	7.5
26.1	41.4	40.7	8.2
24.4	35.1	34.7	9.0
So I could not have expected lower errors by boosting younger teams' expectations.
Older players should not be getting better -- not even possible? -- but they may be improving their teams beyond what their stats would indicate.
Any other theories?

Look at your ages - 24, 26, and 28. Most aging curves will have players improving during this whole time period. The teams full of 24 year olds have 3 year guys who may not last longer in the league. The 28 year old teams are (usually) ones with proven players, they aren't going to give too many minutes to older guys if they are a bad team. There are so many guys who never make it to age 28 (calling that peak age) that the league is full of guys who are young, and never hit their NBA peak.

Brief survey of impact by age band.

viewtopic.php?t=10241#p44121

Young guys hurt on average, thru age 28. With exceptions of course.

Distilling last season's Improved spreadsheet (from 2024 to '25) by players' age, there are interesting trends.
To smooth out the results, I've averaged 3 years centered on a single age cohort: The 20-21 line is an avg of 19-20, 20-21, and 21-22. Showing total minutes (in thousands), eWins per 484 min. (1.00 is avg), and total eWins.

Code: Select all

. ages    1000 x min.     eWin/484        eWins
20  21    24.3   25.5    .85    .90    42.6   47.4
21  22    35.0   37.6    .95   1.04    68.5   81.1
22  23    43.7   46.6    .97   1.03    87.9   99.5
23  24    48.3   52.0    .98   1.04    97.4  111.7
24  25    54.1   53.6   1.01   1.05   112.5  116.1
25  26    49.3   47.4   1.08   1.10   109.6  108.1
26  27    48.8   45.5   1.11   1.10   112.5  103.6
27  28    41.8   40.1   1.11   1.09    96.2   90.3
28  29    40.7   36.9   1.15   1.10    96.5   83.7
29  30    32.9   28.9   1.09   1.08    74.5   64.4
30  31    30.3   25.2   1.07    .98    66.8   51.1
31  32    22.5   17.9    .99    .90    46.0   33.3
32  33    20.3   15.5   1.06    .99    44.3   31.5
33  34    13.1   10.1   1.13   1.14    30.6   23.8
34  35    13.7   11.6   1.15   1.19    32.5   28.5
35  36     8.5    7.3   1.17   1.22    20.4   18.5
36  37     7.6    5.8    .98   1.01    15.3   12.2
Biggest improvement is from age 21 to 22 -- e484 columns -- starting to decline from 26 to 27.
Minutes peak even earlier at 24-25.
Beyond age 33, minutes drop sharply, but remaining proficiency perks back up. Still, total eWins drop steadily from age 25.
Maybe old guys just know how to win the close ones.

note: Only players who played both of the last 2 seasons are in this sample; no rookies of 2025, nor '24 players who did not continue to '25.

Kevin Pelton's minutes projection for the season. I did use them last year, saved time if nothing else.

Subject to change.
All 4 were too high by 30 to 55 wins, so were scaled down to 1230.
Then they are regressed toward or away from 41 to have 7.0 avg deviation; it just feels about right.

I will get the CraftedNBA Projections in here later today. We should attempt to grab BBall Index and DARKO as I remember they wanted to be involved last year but were too late - maybe i'll message them on X. I assume we will use those Pelton ESPN Bet as a stand in for "Vegas"?

If no objections, I submit a "subjective" prediction slate. It's just eWins rounded up/down plus a few beyond just rounding. Biggest difference is Denver, where their projected 5 thru 8 players -- Cam Johnson, Hardaway, Bruce Brown, and Valanciunas -- are all incoming and likely to out-perform last season via the Jokic Effect.

Code: Select all

west   W      east   W

Por   32      Cha   31
NOP   31      Brk   26
Uta   24      Was   20

Note: If you use these team abbreviations, not case-sensitive, they will be in the same alphabetical order as their full names. It's very nice to be able to order them consistently this way.
