I left Baseball Prospectus — and let me be very clear: I left — for a number of reasons, but the most significant is that I have impossibly high standards for my work. I’m wrong a lot. It’s the nature of what I do, but each instance burns me. There was an episode this summer where it was clear the goals of the organization and the goals I had didn’t mesh any more. I can’t say any more about that, but it was the final straw for me and at that point, I began the process of leaving. In the end, I bought myself out of the contract and sold back the equity I had earned in the company. It was a better option for me not to write at all than continue to write there.
