This is the type of thing that could trigger a federal investigation into the whole BCS system (not here to argue the merit of such an investigation, just saying I could see it happen). As a result, if I were the head of the BCS, I'd make a big example of the Fiesta Bowl and blow the whole thing up to show some standards and ethics (ha!).
The funny thing is NO ONE is surprised it happened. The Bowl system is incredibly corrupt. I'd be surprised if there wasn't a bowl with kick-backs, renegade bowl executives, unmanaged accounts, etc. When something makes absolutely no sense that it exists given the alternatives in the market place (i.e. a playoff), there are payoffs and kick-backs all over the place.
