I would recommend to grind for Jaren Jackson Jr as mentioned above. He is at the same level as KAT and better than Sabonis.
For PF, Warrick is a good budget player. He is better than Odom in my opinion.
Sell Sabonis and pick up JJJ. Unstead if Lavine pick up GO Billy Ownes.
Billy Owens is a great defensive player and slasher. When you badge flexible release, he is also a great shooter.
I suggest getting Ruby Kevin porter jr if you don't wanna spend too much other than that just follow what the others have said
also try getting sidney wicks for pf really good defender with a decent shot
thx for the advice
