In the below I am unsure of my understanding of the third sentence.
To tell the truth, our team's ace attacker and setter aren't getting along well.
An attacker and setter not getting along well in volleyball is as bad a situation as a pitcher and a catcher not getting along well in baseball.
At the moment, the attacker is not in their best form, and she is blaming the setter every time she makes a mistake.
It's true though that the setter is a beginner so she doesn't always set the perfect ball.
Is the third sentence saying that the attacker isn't playing well (and therefore making mistakes), and then blaming the setter for them?
