with the type of scholarship. If it's a full scholarship, the athlete will get $4,500. If it's a partial scholarship, he/she will receive a percentage of the stipend equal to his/her percentage of a full scholarship.
At least that's how the P5 will pay the stipends - none to non-scholarship athletes. I doubt that BYU would lessen the impact of the stipend by reducing the amount that full and part scholarship athletes receive in order to cover those without scholarships.
