Despite what UU coaches tell recruits, you can't get the 'BYU experience' at any other school, so for kids who want that kind of holistic approach where the school invests in your personal & spiritual growth (and sees you as more than an employee who can help win games), BYU is a good place to come and stay.
You can get coaching and training and partying at almost any of the 300+ Division 1 schools, but none of them can replicate what BYU offers (especially to LDS kids).
