I think you are going way overboard here. Vidro is an enormous risk, but at least he brings along with him the chance for very good production. With Neifi you are guaranteed crap. And Neifi would always be the fallback if Vidro did indeed fail. Trading Corey for him would be a risk, but nothing close to a guaranteed failure or dumb. I would rather take the chance of getting something out there than guarantee absolute failure, which is what Neifi does. If Vidro cannot play, which many close to him are sure of, Neifi becomes a much better option. That's not going overboard, that's being realistic. Neifi at 2B is better than playing with 8.
