Can I answer, please? I would pay ZERO, nothing, zilch additional $ for additional oversight. The people that were already there (coaches, admissions staff, athletic department) failed to provide appropriate oversight, in many cases. Yes, mistakes are made, no one is perfect, but they did not do their job. For example ...
At USC, a non-kicker made the admit/walk-on list/roster for football. I know several people who have played football at USC, including ones that were "walk-ons." This list is a very closely controlled and monitored list by the coaching staff. You do not accidentally end up there, or go unnoticed once on.
At UCLA, a non-recruited "soccer" player (I am being generous) received an athletic admit and was included in the women's soccer roster and media guide. Those guides and rosters are edited and reviewed by multiple people including, in most cases, the coaching staff.
Choose the explanation -- complicity or incompetence. They failed to provide the appropriate oversight of their programs, or exhibited extremely poor judgment.
