This started as a comment on Grant's Bisbee's piece of a few days ago on the same subject, but it took on a life of its own...Either way you slice it, the dominant Tim Lincecum that won two Cy Young awards has seemingly vanished into thin air. The reasons are complex, and not plainly obvious. I think Bisbee has nailed the best take on this, but I also think he’s missing one important factor. I intend to bring out that point as I walk through his points.
