Sure, if the owner has decided not to spend any money at all on free agents and the only way we can get good is to build entirely through the farm, we should trade LuBob.
But if the young pitching continues to come around, and the owner is willing to spend the amounts that he was willing to spend when Hahn was in charge, we should keep Luis Robert and we should sign two or three quality free agents who are not relievers and try to win this thing in a couple of years.
