Thrylos, I don't find your thesis absurd. Yet, I'm also not willing to subscribe to it just yet either because I'm sure we can find several pitchers whom became better when with the Twins and worse upon leaving. I'm only going to look at dramatic (.5 ERA) differences when considering the pitcher as better or worse, because smaller amounts are a difference in degree not kind, and I think you are trying to expose how pitchers become a significantly better pitcher post Twins. I did look over your list carefully and have never figured out why we let Breslow go. Money? I don't recall. In summary, I enjoy an argumentative thesis, and you have an interesting one here, even if it's a little long on the claims and short on the evidence (I'm speaking of balance here).
