Here's the issue that I still have. You just projected 7 prospects (including Plouffe) to become average or better players. That is an impossibly high success rate even for top 25 overall prospects. I am really excited about what the Twins have going on in the minors but it will probably take a little more time unless Ryan can have another Willingham/Doumit type offseason (or two of them).
This projection assumes Parmalee, Hicks, Arcia, Gibson, Meyer, Herrman figure out how to be at least average by 2015. This gives those 6 2 full seasons to figure things out, which I would assume is plenty of time considering how close all of them are anyways.
