Derek Zumsteg of U.S.S. Mariner has an interesting post up discussing the two schools of thought for evaluating a trade: at the time of the deal based on what’s known, or just on the results of the trade. Take the Liriano/Nathan/Bonser/Pierzysnki deal. If you look at the trade in the context of November 14th, 2003, it looks very different.
