Jackson provides JsonDeserializer and its subclasses such as StdDeserializer to deserialize objects from JSON. Jackson Databind has internal dependencies on Jackson Core and Annotation. Such data can also be stored as text, but the JSON data types have the advantage of enforcing that each stored value is valid according to the JSON rules. We can write our own JavaScript function to check if a deeply nested property exists in an object. Another tricky point is the fact that's players is an object and I want it to be an array.
