That is some really terrible logic. The DeRosa trade went from an okay one to a pretty good one given the performance of all 3 guys this season. Expanding upon this, the DeRosa trade in and of itself was actually pretty good in terms of the return we got. Archer, Gaub, and Stevens have all performed nicely. The decision to sign Miles was the mistake, however, Miles's suckitude should have no bearing on the evaluation of the DeRosa trade, because they are separate moves. They were seperate moves that were made in conjunction with each other. There's absolutely nothing wrong with evaluating them together. The only reason they trade DeRosa was to get more left handed, the only way they got more left handed was by replacing DeRosa with Miles. Every trade involving major leaguers for prospects has to weigh the cost/benefit of the present/future. This was an absolutely horrible short-term trade. Without question. It was a disaster. Longterm who knows. But people are getting worked up about bullpen prospects, those guys are a dime a dozen.
