Of course, this raises the question: given that we were in the Big Ten championship hunt on a near-annual basis for 40 years, why was it necessary to undergo a complete philosophical overhaul?
IMO, RR's big mistake was to come in here and to act like he was taking over for a fired coach. When you take over for a guy that's fired, you generally want to clean house and start afresh. But that's not what happened here. RR was replacing a very successful coach, whose program may have needed some tweaking, but still had basically a solid foundation. He probably should have retained more of Carr's assistants, and worked to accommodate more of Carr's players instead of adopting a my-way-or-the-highway approach that led to massive attrition. He rolled the dice with the approach he took, and we can only hope that there will be a long-term payoff that makes the last three seasons worth it.
