Detroit and Texas pull off challenge trade

This is a classic challenge trade, my position player for your position player, both guys with huge contracts but who are also coming off disappointing years -- or in Ian Kinsler's case, two disappointing years. In the pending deal that sends Kinsler to the Tigers and Prince Fielder plus $30 million to the Rangers, Texas gets the better end of the trade in baseball terms, I think, but that assumes that Fielder's miserable 2013 was more about bad luck and personal troubles than a sudden, early collapse of his skills at age 29. And there's more to the deal than just the immediate on-field impact.
