If this was for academic reasons, I'm shocked.
Yes, BYU tends to have higher ethical standards than other schools when it comes to academic eligibility, but there is still so much offered to athletes, particularly the football players.
Things certainly could have changed in the last 15 years, but my wife who was a BYU athlete laughs anytime a football player can't make his grades. There's an entire army of tutors available for the athletes, with preference given to the football players. According to what my wife saw, players basically just had to show up and they'd get all the "help" they needed to finish their homework. If for some reason a football player still struggled, the player would basically get their own private tutor.
Athletes have their own computer lab, study hall, tutors, and just about everything else at their disposal. All T-fab would have had to have done is show up at student lab.
