In keeper and dynasty leagues, the loser forfeits their first-round rookie pick or slides it back a round the following season. It hits where fantasy players actually live: future value. The main deterrent leagues use against December tanking, because it makes losing on purpose expensive.
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.
