Meh, Valbuena has made a grand total of 34 starts there, only 7 of which were last year. That seems pretty irrelevant. I'd also consider Desmond a better (and more consistent) hitter outside of 2015, DRAMATICALLY better baserunner, and a better overall fielder in general. For what it's worth, Steamer has Valbuena at 0.3 WAR and Desmond at 1.5 WAR.
