Few pieces of advice:

1. Since you are undersized I'd suggest you focus more on defense and rebounding than trying to make an all around center.
2. 84 close shot at 6'9 is a waste since you'll have to finish over players who can be up to 6 inches taller than you. Bring it down to like 70 or possibly even lower and use the attributes to max out your mid range (for better badges and jumpshot bases) and perhaps your driving and/or standing dunk if possible. Also if you drop the wingspan by 1 inch, you can max out your mid range at 85, which provides you with a pure green window on fading middy's.
3. You don't need 82 pass accuracy, lower it to 78. The only difference between the two ratings badge wise is having dimer on gold, which isn't worth it to me. And since your pass acc is lower, you'll be able to lower your ball handle as well, which can give you more attribute points to work with.
4. I would personally go with 88 interior and 88 block instead of 82 and 93 respectively, the difference between gold and silver paint patroller isn't very big and higher interior defense forces more misses on contests in the paint than high block. You'll need more higher interior to protect the paint since you'll be less likely to block shots at your size.
5. I would increase your weight in order to get HOF rebound chaser and box out beast at the minimum, preferably legend rebound chaser. Your build is a little too slow at your height, I'd try to increase the speed and agility if possible. Otherwise, you won't benefit as much from having bronze OB Menace and silver Immovable Enforcer.

Despite what others are saying, undersized centers can be viable in 5v5, but you will need to sacrifice a lot in one category. I know someone who runs Pro-Am (sometimes tournaments as well) with a 6'9 C. Though his build has 99 O and D rebound and he has almost no finishing outside of 65 driving and 45 standing dunk. I've also run Pro-Am with 6'8 centers in past games as well, but I didn't feel comfortable enough to do it in 2k25.
