DePo put out an explanation of the Jody Gerut trade on his blog, though it doesn't do a very good job of convincing me.

Over at FanGraphs, Cameron takes on the individual reasons DePo offers up FJM-style, and also doesn't find them to be too convincing. The only reason he seems to buy in to at all is making room on the roster, but it's still not enough to make it anything more than a seemingly insane trade.
