I doubt he's waiting on admissions. He's a great student with solid work experience and any of the schools he's looking at should bend over backwards to get him.
His nfl future is entirely dependent on this decision. Most of the coaching staffs he's rumored to be considering have had shakeups of some sort or another this past season. I'm sure he just wants let things pay out a little, find out a spring ball goes etc and see what the forecast is for these programs.
If he can't play spring ball, what does it matter anyway? Hoge and Lil koy will get the backup reps and Taysom will make a decision before fall camp. Probably even after this semester ends so he can start summer workouts with his new team. For now he's still enrolled at BYU. I'd love to know one way or the other tomorrow but this guy has done enough for BYU to deserve the time to make the best decision for his future and not feel pressured by anyone, especially not fans, to do so.
