My $.02 worth: I think it is very sad. I love the CG hire, and I understand the demotion, but I think if TR was willing to stay you at worst freeze his salary at its current rate, but cutting it was probably the last straw. I can't blame TR for leaving.
I HOPE TR was wise enough to insist on a 2 yr contract rather than the std 1 yr. I HOPE that Duke goes 2 - 9 next year, but the defense plays tough and they end up giving Ted the HC job.
