Rules question

Sorry, I’m an Ottonewb: I understand I must have 2 C on my roster every day. Must I have 2 C in my starting lineup every day? Given games played maximum, it would seem preferable to usually have a great C and a blank in starting lineup. Legal?

Section I.f.xi: The lineups page and roster organizer for non-head-to-head leagues allows for 2 catchers for platooning purposes; Ottoneu is not a 2-catcher game.

You do not need to have 2 catchers.
