I don't understand why Jaylen's on/off numbers are so bad.
I can see why his offensive impact would be lower than people due to average scoring efficiency + middling passing ability + middling spacing.
I can see why his defensive impact is lower than one would expect because his team D is not as strong his man D. Man D tends to get a lot more attention.
Still, even though I can see why his impact numbers would be lower than you might expect at first sight ... I still do not understand why they are as bad as they are. That confuses me. I don't understand it.
I tend not to use these numbers much for Jaylen because I don't think they tell the true story of his talent & impact.
I think most of Celtics nation has basically chosen not to use these numbers for Jaylen, especially since he elevated his play so much in the 2024 playoffs. The Jaylen that can stop a player like Luka, hit buzzer beater 3s, and get tough baskets against set defenses in the highest pressure settings doesn't need analytics to analyze his play. It's been proven and it resulted in this team winning a championship.
I guess what needs to be decided moving forward is if we still think Jaylen is that guy and can he elevate his play to the highest level or will he flame out like he did in 2023, 2025, and 2026? It's not an indictment on Jaylen - he's not even considered the best player on the team - but when the best player has gone down, he has unfortunately wilted in high leverage situations. Situations we use to not bring up stats like on/off.
Where some people see tough shot making, others see unneccessarily tough shots. Is White's fast decision making, connectivity, and ability to make his teammates better more valuable? Where some people see Jaylen's tough 1-on-1 defense, others see his lack of team defense. Sure, White has a lot of wow plays of his own with his rim protection, but team defense is something that White excels in.
That could help explain why Jaylen might score well in categories that the average viewer sees, but White actually does better in all of the 'little things'. And those little things might possibly be more helpful in actually winning basketball games.
