I would lose all faith in management if they move Nico for an underwhelming haul. He's under control for 2.5 years at $11.6m AAV (age 27), playing with a fractured hand, and still on pace for 3.4 fWAR per 150 games. Their return value should be that of a cost controlled cheap player, in his prime, who will probably get you around 10 fWAR from this point forwards to the end of his contract.
