If the Nats and LaRoche are going back and forth about a third year, I think the Nats should take LaRoche on three years. Three years gives you more time to evaluate Rendon and see what Espinosa can give you. If Espinosa breaks out like Desmond, then Rendon has to wait for an open infield spot. If Espinosa continues to struggle, you have time for Rendon to learn 2nd base. After the third year you either use Moore or potentially Skole everyday as your 1B if they show they are regular everyday MLB players.
