Re: James Shields and Wade Davis traded to Kansas City
I think it's a very smart trade for the Rays. They weren't going to win anything in the AL East for the next two years, with the Blue Jays making huge moves, the Orioles still riding their playoff high, the Red Sox beginning to reload, and the Yankees being the Yankees.
Now they are rebuilding a window for success from 2015-2020. I wouldn't be surprised to see Price go next for a boatload of guys that can help for that window.
As far as the Royals go, they are kind of like where the Reds were five years ago in that they can produce decent hitting prospects but have no real pitching to speak of whatsoever. In a way, this is kind of like the Royals equivalent of the Hamilton-for-Volquez deal, only Myers is less proven than Hamilton was and Shields is obviously a lot more proven than Volquez was. Therefore, I don't see it as completely one-sided, although if I had to choose I certainly prefer the Rays side of this deal.
Interestingly, this is somewhat akin to the inverse of what Tampa did when they shipped out Delmon Young for Matt Garza. That one worked out pretty well for them- I'm guessing this one likely will as well, it's just that we might not see the real dividends until 2-3 years from now.
