A filmed mock job interview where the champion, in full HR mode, makes the loser formally re-apply for their spot in the league: resume of past seasons, references, 'where do you see your roster in five years'. The hiring decision is read aloud in a letter. Business attire required.
Budget note: this one costs nothing but dignity, which makes it a strong pick for leagues that would rather spend the pot on the champion than on the loser's downfall.
