I'm pretty sure buyout plays no role, maybe a very insignificant role at best. What matters is consistent improvement, which both RR and Harbaugh have displayed. And, since RR is currently our coach, why would we exchange him for Harbaugh? Only two reasons I can think of is the violations, and RR not being a "Michigan Man" (whatever that really means). Do those really cause for a coaching change? Doubtful.
