I think it is hard to put a value on Embiid these days because he misses so much time. For me, it is clearly Jaylen over Embiid accounting that.
However ...
When Embiid is healthy, who is better?
It is even tough to say what a healthy Embiid. He spends so much time out injured. Then he spends another chunk of time playing himself into shape. Then he has period where he is healthy-ish which appears to about as healthy as he can ever be at this point in his career. Is that Embiid better than Jaylen?
How good of a defender is that Embiid? He is not an All-NBA defender anymore. His defense is more uneven than ever. Perhaps similar to Jokic. Embiid is good when he can stay near the rim but gets in trouble when he has play defense out on the floor. He struggles to deal with the PnR or handle switches against ball-handlers.
His rebounding numbers have dropped. Only 8rpg in 31mpg. He used to be an 11-12 rebounds guy.
His scoring volume is still high. Almost 30pts per 36min over the last 2 years. His scoring efficiency has dropped off but is still strong. He was a 63.7% TS from 2020-21 to 2023-24 down to 59.7% the last two seasons. It was 56% TS in the playoffs this season and that was with dream matchups against inadequate defensive centers on BOS.
Is Jaylen the better player than this? I think he is.
