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.

On Dec. 8, the Nets had the 7th best record in the East, along with the 5th best point differential.

They had a few players in early editions of the 'most improved' list. Since that time, their fortunes have changed significantly.

Their early TotalReb% would be top 5 if they'd maintained it. Their latest 1/3 TRb% would be next to last.
