The league sentences the loser to be better: update the resume, get the overdue physical, read one classic novel, and report back with proof. A punishment disguised as an intervention, invented by leagues aging into their thirties. The loser is furious and, months later, quietly grateful.
The long haul: this is not a one-afternoon sentence. With a time commitment of one month, 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.
