I've read that article. It does not back up your assertion that the Twins would replace Kepler and Burdi with zero WAR players, which is our point...... It is Fernandez plus two other players, compared to Berrios, Burdi, Kepler. If you trust TR, I would think you trust him to find players worth more than Zero WAR to play whatever position you think Kepler is going to play. It also discounts that, if you wanted to, you can trade Fernandez after 2 years, and get other players back. Your WAR projections pretty much ignore all the context, and just compare those three players in a vacuum.
