How to call the "rugby scrum" in the paint...

[whistleblower]

I usually look for the "outside" player and call the foul on her. "outside" meaning the player who is the third or fourth player into the scrum, far away from the balll, who just basically climbs on somebody's back to try to get a hand in. Keep calling those, and the action eventually clears out to just 2 or 3, and you can really see the fouls then.
