LDS talent feels entitled to something more at BYU be it playing time, position, security in "their spot".
I remember the story of Bret Engemann's mom coming down to the football office and going off on Crowton and offensive staff when it was looking like Engemann wasnt going to start.
I know personally of another highly recruited QB who's family had that same mentality and made themselves look really bad.
It does seem to happen more with the QB position but its also happened at the TE spot too.
