I don't see any way the Rocks keep Arenado. They simply cannot afford the risk of offering a player the type of long term, $200-300 million deal he is likely to command. If Nolan got three years into such at deal and started breaking down at 32 the Rocks would be screwed. Given that reality the Rockies should be looking to trade him this offseason while his trade value will be at its highest. That will free up another $18.5 million in payroll next year. Hopefully Charlie Blackmon's age will work against him and the Rocks can get him to sign something like a four year, $100 million deal. If he posts another year like this one he may become another $200 million player that Rockies cannot afford.
