[just another ref]

With regard to advantage gained, we still must see the bigger picture. A1 makes a throw-in waits a few counts then sprints down the end line around a double screen, catches a pass and hits a three. Clear advantage gained and an easy call. But, they run the same play, B1 recognizes it and switches to pick up A1. A2 make a backdoor cut, receives a pass and shoots a layup.

The offending player doesn't have to be directly involved in the play (touch the ball) to create an advantage
