The loser wears a shirt bearing the champion's name and face to every league event all season, like a fan of a one-person team. New champion, new shirt, same loser if things go badly again. The champion signs it, unprompted, repeatedly.
The long haul: this is not a one-afternoon sentence. With a time commitment of full season, the punishment keeps paying out (for everyone else) long after the season ends. Long sentences need a written end date and a league-appointed enforcer who checks compliance.
