Haha, yes we are!! But to play devil's advocate in favor of Fearless and Mdot, we do subsidize every coach salary through our tickets, apparel and cable packages. So despite being unreasonable morons, there's hope to forgive ourselves.
BUT that doesn't change the fact that Harbaugh isn't paid [x million] to [insert accomplishment]. He's paid his salary because Michigan hired him. It may seem boringly simplistic but that's actually the full and only reason for his salary. He'd be paid less at most other schools and his successor will be paid as much or more.
Any Michigan fan complaining about Harbaugh's salary/accomplishment ratio should either go the full step and recommend he be fired or just stop. Given the 10-win seasons after the Hoke/RR eras, my recommendation is they stop.
