I really do not see how anyone can want CarGo or Fowler unless they only do a cursory surface analysis of them. That makes me nervous as to why Rizzo would be interested 
I've mostly liked his moves up to this point so perhaps he knows something I don't.
I think anybody who looks only at their home/away splits and presumes that you're getting the away player probably is underselling the Nats diligence process.
Just because Coors makes you a better hitter doesn't mean you were a terrible hitter. To some extent most players have a better home vs. road split. Coors just exaggerates that effect. How much it exaggerates is a matter for a lot of detailed analysis.
Remember the folks who argued that Gio was a creature of A's stadium? Yeah, that turns out to be not quite true, eh? Same, maybe, with CarGo or Fowler - yes, they look good at Coors, but that doesn't mean they suck elsewhere.
