I had put this in another discussion. The point is that Tatum is clearly making all these other players better. They are all quite a bit better when on the court with Tatum than without (Horford notwithstanding who is about the same).
I think as others have pointed out, Tatum is trying to change his game so that (1) he is not so reliant on the 3 and (2) he is in a better position to make others better. It seems to be working.
As to free throws, it is nothing new. It is something he should work on. I suspect that it isn't a top priority for him and it probably shouldn't be. Same with the 3s. He always seems to go through stretches. Not sure what you can do about that. Maybe focus on taking more "good" 3s and fewer contested 3s. He has been at 35% 3P% since 2021. Some of those are always end of the shot clock, low percentage shots.
Wasn't sure where to put this but I wanted to see how various players performed in terms of +/- with and without Tatum. Tatum is clearly the best player. How much is he making other players better, who makes Tatum the best (note, this excludes the last game vs. ORL)?
Brown + Tatum +92/550 min
Brown - Tatum +15/200 min
White + Tatum +165/515 min
White - Tatum +22/140 min
Prozing + Tatum +107/440 min
Porzing - Tatum +5/105 min
Holiday + Tatum +136/629 min
Holiday - Tatum +10/102 min
Horford + Tatum +78/420 min
Horford - Tatum +25/130 min
My overall take away from this is that Tatum is clearly making everybody better, but not all the same. Everyone has more minutes with Tatum than without so you could normalize these per36 or per100 poss., and if you did that, only Horford would come out about the same with and without Tatum. It is also of note that Brown plays the most without Tatum, which makes sense. You want the other primary scorer on the floor when Tatum is out.
If you look at this the other way, what player makes Tatum the best, that is White. Tatum is +175 overall and +165 with White. Tatum achieves most of his positive +/- when he is on the court with White. Holiday is the next best Tatum facilitator (+136 Tatum with Holiday). Neither is surprising, that the better ballhandlers are the ones that allow Tatum to be at his best. There is some overlap as Tatum, White, and Holiday are all on the court fairly often. Maybe I will try to filter that out some other time.
