In auction keeper leagues, the loser must re-draft their most expensive player from the failed season at the same price, locking last year's mistake into next year's budget. One documented league forced a $65 re-buy on a declining star. Cruel, clean, and entirely self-inflicted.
The long haul: this is not a one-afternoon sentence. With a time commitment of next 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.
