I'm sorry, but this sounds like poor contextual awareness of the defender. Like IRL, you don't keep attacking the Ben Wallaces, Shaqs, Mournings, Mutombos, Artests, KLs, MJs, etc of the NBA and not expect them not to have some type of mental impact on your game.
You're shooting 60% to 70% from the field against "regular" players, but you don't have a problem with that; however, you play against a defensive-type player, and it's problem due them lowering the quality of your shots?
That's on you to change your gameplan or role, so that you're not meeting the defender in their battlefield and/or having a different impact on the game.
As many badges that awards bad offense...wow.
