I probably know more then most about BYU to BIG XII and really that deal got totally botched and not by anyone in the athletic department.
That said, the biggest issue BYU has right now is losing too many football games. If BYU had gone 11-1 or 12-0 last year with the schedule they had (very doable in my mind). Not many people would be complaining right now except for us not making the playoff.
