AI ignores players versatility and sticks to their assigned role as the most important rule when selecting their starting lineup no matter the quality of the players in their roster.
Most notable example is Atlanta who keeps Trae Young on the bench because both he and Dejounte Murray are listed as PG. Instead of playing them both at the same time as PG and SG.
Another example are Minnesota who have two high profile Centers in KAT and Gobert and refuses to use them at the same time.
This also leads to these players being easy to be traded away. For example I got Dejounte Murray for 1 first round pick + 3 star player. Tried the same with Minnesota and got KAT as well.
As a workaround please change Dejounte Murray to SG and KAT to PF if there will be another update of the game soon.
