Honestly how would I even catch someone who did this? It's easy to check for WR running the ball, just check the rushing leaderboard.
You'd have to watch the game film. It's the only way I know of. I'm not asking anyone to do that. That's why I wanted the point made that it would not be acceptable behavior here.
If believe if you download the game log you can see players lined up out of position, such as a WR at RB/FB.
