League comissioners in Fantasy Football can configure their league draft as either live or autopick. For live drafts, they can provision it as auction or traditional. From the game and league resources, we aren't seeing any XML differences between an auction league and a traditional league. How do we find out which one is configured in a live league?
Good point. I've added in a field, "is_auction_draft" to appear just after the "draft_type" field in the League settings subresource. Should be available roughly next week or so. It'll be a "1" if it's an auction draft, "0" if not.
