I'm not a big fan of using hindsight to judge trades. I understand things can change, but it's hard for me to give credit for things that happen years from now. I think you judge be what's known at the time of the trade. I wouldn't hold it against the Twins if Alcala gets hurt, you can't know that in advance. But I also am reluctant to give a whole lot of credit if he turns into a valuable reliever. You can't know THAT, either. Judged by how it affected the teams at the time of the trade, and the year or two after, it was a pretty awful trade, IMO. Unnecessary, also.
