The loser hosts next year's draft and funds everything: food, drinks, supplies, cleanup. Their home, their wallet, everyone else's party. The league's food orders get noticeably more ambitious when someone else is paying.
Budget note: this is one of the expensive ones. Decide before the season whether the loser pays, the pot pays, or the league splits it, and write that down. Money arguments kill leagues faster than collusion.
