One key element is the family bond. Their shared love for wrestling keeps them together through thick and thin. Another is the training. They must have had some unique training methods passed down in the family. And of course, competition. How they face opponents and strive for victory is important.
In this true story, the family's passion for wrestling is a key element. It drives them to keep going in the face of difficulties. The element of sacrifice is also there. Family members might have sacrificed normal family time, educational opportunities in some cases, for the sake of their wrestling dreams. And the growth of the family in the wrestling world, from beginners to established wrestlers, is an important aspect of their story.
