Working on a Community Projection Review for Matt Morris just now, I encountered this, which I wrote in late February:

You can't exactly tell from the projection, but a couple of you really think [Tom Gorzelanny's season] isn't going to turn out well, predicting that Gorzelanny won't pitch at all this year. (And both people who said that said it before Gorzelanny missed a start with shoulder tenderness.) I factored in those projections by counting the zeros in innings pitched, strikeouts and walks, but not in ERA. Nobody took the next logical step, which is guessing that Gorzelanny will pitch hurt, deny that he's hurt, and stink up the joint, so the ERA and rate stats above probably don't reflect some of the pessimism here.

I certainly make my fair share of bad predictions, but that one was pretty good.
