I don't know what you're saying in the second paragraph. Can you please explain?
EDIT: In earlier builds of the roster, I used that tendency in conjunction with the Set Screen Tendency frequently but noticed that when you have players with more than a 0 in Set Screen Tendency, it caused a lot of screens to be set in the low post among big men and they would flash-screen in the low block. I hated that as it's completely unrealistic.
What I've realized is players with a Use Screen Tendency above 0 will automatically "call" for a screen to be set when they want it. I would suggest using the Use Screen Tendency but not using the Set Screen Tendency. With the tendencies edited that way, players will use screens more appropriately but the inappropriate use of setting screens is minimized/eliminated.
If you have any questions, let me know. I'm not sure if I've explained this clearly.
