What's hilarious is your certainty CRB must be doing something "extra" without citing any proof. You do understand there are other factors and dynamics at play and that both may be true - players are getting something "extra" while CRB is not directly involved. If you have paid any attention at all to college athletics over the last couple of decades it has become very clear that boosters and assistant coaches know what needs to be done and they do it in ever more sophisticated ways to hide it. To automatically assume the head coach must know, let alone be directly involved as you have claimed, is a bit naive based on the empirical data (and, yes, some head coaches are stupid enough to be get involved a la Will Wade but most are smarter than that).
While your claims may ultimately be proven true, my guess is CRB is not directly involved at all and he is not aware of any illegal activities. Lastly, everyone assumes some kids are getting something extra in any major college sports program so that is not a novel concept.
