The linked MSNBC story blames Mike Garrett for Cheat Pete leaving. With convoluted logic that would make Senora Ross a tough grader, the writer (Keith Arnold) disparages Garrett for being "asleep at the wheel" during the Bush affair "and plenty more minor blips on the NCAA radar." This apparently caused the deteriorating relationship between Carroll and Garrett.
So we can logically conclude from this that had the Athletic Director been proactive about dealing with Bushmayogate and all of the other "minor blips" (e.g., Jarrett, McKnight, OJ and an extra coach on the sidelines, etc. etc.), then Cheat Pete would have a great relationship with Garrett (akin to Barkley or PlaSChke) and would be turning down $ 35M so he could stay at the University of Sports not College. In fact, we should assume that Cheat Pete was begging Garrett to loose the Compliance Department and publicly display all of the findings, but that unethical Garrett wouldn't do what ethical Carroll knew was true and right.
I can say that I learn something new each day!
