I think the fact that a shoe and apparel corporation is involved (which could logically lead one to conclude that there are others... like Nike?) is what prompted the feds to get involved. To me, it reveals a level of complicity that goes beyond a handful of assistant coaches and one big-name head coach being offered up as collateral damage.
Nevertheless, the NCAA rules committee (imo) should be gutted and replaced. They've pretty much sat on their hands over the past two decades and refused to deal with the countless recruiting violations/academic violations in lieu of protecting big-name head coaches in Div 1 athletics.
Rick Pitino has exhausted his get-out-of-jail free cards within the NCAA in recent years, and is now looking at a federal indictment which could involve a considerable prison sentence.
But at the same time - he's just one of several who've committed similar violations, and I'm looking forward to seeing how far the shoe drops and who else gets implicated.
