Kepler and Walker have options and they aren't ready anyway. And while DH isn't the most pressing need, assets are fungible. This signing (knock on wood) will grow the Twins talent pool, that is a good thing. Even if no trade is made this winter, Its hard to envision a casualty to this except Arcia and that is assuming a. none of Mauer/Plouffe/Sano/Park gets hurt in the spring, and b. someone actually claims Arcia if he's exposed to waivers which would be dependent on his winter/spring performance and lingering health questions. History shows us that gambles on players in nascent markets can pay off huge. Personally I can't think of a better use of the FA budget than this and I don't understand any reaction except huge kudos to the Twins for taking a smart gamble on growing their talent base.
