I didn't have a specific plan for or expectation of low yr to yr change but I guess it happened to a degree of 2nd least.

Sixers without Embiid this season are 9-18 and -5.5 ppg. This is better than only the terrible 5 and equal to the Grizzlies.
The b-r.com forecast has them going 12-9 the rest of the way -- Memphis 7-13 with a lighter schedule -- to finish with 47 wins, 6th or 7th in the East.
With 5 fewer wins, they'd still be #8. Embiid may return, of course; but perhaps a bit shaky, or a lot.

As the over-reaching teams refuse to lose, and the underachievers can't even beat one another, we've matched our mid January futility level, averaging 7.41 MAE

Our worse half has worsened less than the better half; and the bottom-top diff is down almost a full point from early Feb.

On Dec. 8, the Nets had the 7th best record in the East, along with the 5th best point differential.
https://www.basketball-reference.com/fr ... &lg_id=NBA
They had a few players in early editions of the 'most improved' list. Since that time, their fortunes have changed significantly.

Dividing their 69 games played into thirds (of 23 games each), here are some team rates:

Code: Select all

W   L    ORtg    DRtg    TS%   TRb%   Stl%   Blk%     eFG%   TO%   ORb%  FT/fga
13 10   119.3   116.2   .583   52.0   6.3   10.4     +.026   +.9   +3.2   -.015
6  17   113.8   118.6   .550   49.1   7.7    9.9     -.035   -.7   +1.6   -.035
7  16   111.2   117.4   .556   47.4   7.6    8.0     -.031   -.5   -2.0   -.033
https://www.basketball-reference.com/te ... -advanced/
These last 4 columns -- the Four Factors -- are represented by team-opponent differences. They've cut down on turnovers!
Their early TotalReb% would be top 5 if they'd maintained it. Their latest 1/3 TRb% would be next to last.

ORtg-DRtg has gone from +3.1 to -4.8 to -6.2
Every one of their rotation players has generally declined. Top 8 minutes guys in the same 23-game periods:

There are 13 entries this year who were also in it last season. Year to year has a negative correlation.

There are distinct tiers now: the 5's (party of one), 6's (gang of 4), 7's and 8's.
Also, #1's lead has shrunk to smallest since Dec. 1

Congrats mediocre, hit us all out of the park.

I went back to review my numbers. Very depressing reading.
