David Golebiewski of Fangraphs wrote a piece earlier in the week on Andy LaRoche's release and the Jason Bay deal as seen in hindsight. The gist of the story is:
"In retrospect, it looks like the Pirates have little chance of breaking even on the Bay deal, due mostly to LaRoche’s non-development. I have to admit, I liked the trade at the time. Getting 5-6 years of team control over a top position prospect like LaRoche had the potential to give the Bucs a lot of surplus value. It certainly didn’t work out that way, however."
