Some of the guys who Utah has been getting may want to come to BYU and play for Kalani & Tuiaki but they still need to be admitted. That's not just an ecclesiastical endorsement issue, it's also a GPA and ACT issue. BYU is a really hard school and marginal students (even with all the help football players get) don't survive the university and graduate. The academic issue will limit the pool in a way that Utah's isn't limited.
