After thinking about it some more, I think passing both the ContentManager and a SpriteFont into the screen is an indication of breaking the Single Responsibility Principle (SRP).

You signed in with another tab or window. In your first version, it's pretty easy to just pass in a derived class, and have OptionsScreen just use it without knowing the difference.
