Imagine watching a youth 10-and-under basketball game when heavily involved parents begin yelling at the referee. Naturally, the parents believe the ref missed a call, one that could've changed the result of the game.
Most referees in this situation are high school or college kids looking to make a little extra cash for dates or the latest video game. Admittedly they don't have the highest basketball knowledge, still learning the game themselves.
But every now and then, you get a referee who knows what they're talking about — a referee who knows the game better than most people on the planet.
