Thing is I don't think torres is as good a prospect as robbles but time will tell. Secondly as you said it, you have a SS, in russell and he is young, you also have baez also young who could play SS, you have zobrist under contract, you have kris bryant, there is no where for this guy to play for years even if he does develop. Washington that is not the case he could take the place of jayson werth soon enough. fourthly the cubs were the overwhelming favorite with that move last year, if the nats make that move they still might not be the favorite in their own league in my opinion.
