^^ well, kinda, but not completely! I know a girl who was a nationally ranked gymnast who was able to quite genuinely articulate how she had just given up gymnastics and was seeking a “normal” high school life and how BS would allow/encourage her to get the balance her previous life did not. She also had demonstrated she had grit and discipline to have achieved at such a high level in her sport.
So while technically, she was not bringing her gymnastics to BS, she was bringing the person with that experience to BS. Agree there’s no hook in achieving in a sport the school doesn’t have, but it can help differentiate you from the applicant pool.
