You're the GM of a team. You have an outfield of Taylor - Eaton - Robles and the rest of your team is stacked. You're telling me you wouldn't trade Robles for 1 year of Harper if it meant taking you over the top?
No, baseball isn't basket ball. It's rare (nonexistent?) that you have a team where one player actually will put them over the top and anyone thinking they can spot such a situation in the offseason is an idiot
