A 1,000-word handwritten essay titled 'Why I Lost', with footnotes citing specific lineup decisions, graded by the league and read aloud at the next draft. Handwriting requirement prevents AI ghostwriting. Margins are checked.
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.
