Jmo but they should just simplify it to 3 cases:
1) Coach leaves before the kid even practices (ie Miami)
2) Team loses bowl eligibility due to misconduct.
3) 3.0+ GPA waiver (after all, this is the ENTIRE reason kids have to sit out 1 year when transferring...academic concerns).
All 1 time waivers. All this homesickness/family member stuff is silly. Those kids can transfer too and sit out a year. Shoot they probably should take a year off if they have a sick mom. Priorities.
