Over a 4 year period of time that gives you 15 above the the 4 year limit and plenty of room to accomodate the various vagarities such as injury, transfers, early entries, etc.
I could perhaps see allowing perhaps a two year exemption in the case of a new head coach to maybe 28 since there will always be kids who don't fit in with a new staff.
A side benefit would be further dispersion of talent if that is what the NCAA is seeking.
Allowing appeals for "coaching changes, lots of NFL early entry guys, medical or academic losses" would just lead to endless incidents and accusations of bias and unfairness.
I believe his favorite SEC team if Florida, but as soon as they got punked out by Louisville, he became a huge Alabama fan... now I don't know what to think. I'm glad I don't have to shift my loyalties. Could you imagine an ND fan cheering for USC or Michigan just because we play them regularly and they happen to be in a BCS or NC game? To me, that is the equivalent of a Florida/Auburn/LSU fan cheering for Alabama (who should be a major rival) just so they can say that they had the champs on their schedule (or in Florida's case, in their conference). The idea that proximity to greatness does not equate to greatness is lost on them.
