In fairness, we've only had the report from one side of the conversation and from the guy who is in PR mode. In reading the articles coming out of College Station, Texas had been plotting this change for months and Schlossnagle is a grade A *insert favorite derogatory term here*. I fully believe Trev said what is being reported ('it's ok if you want a different job'), but a lot of context is missing and given who is spilling about the conversation, I take the report with a heavy dose of skepticism.
That said, I suspect that Trev won't be staying long in College Station. It's a shame that he wiped out so much goodwill for what appears to be a relatively lateral move.
