Original decision. That it was made by others. His Dad played for BYU and could have been one of those who steered him away from BYU. Other than his Dad, His high school coach would bee high on his list of influencers. The OP gave a very plausible reason that his coach would have guided him away from BYU. Other than his dad and coach, peers may have steered him away, but my money is on his coach.
