I have a random idea: Target for every manager at the beginning of the season.
Say 8 teams in Great 8, then based on last season standing, BB could assign the new target for the new season, those targets could be:
1. Fair enough, demotion last season, but get promotion in this new season.
2. Failed to win relegation series, but either clinch final 64 in national tournament or get promotion within two seasons.
3. Survived in relegation series, target either to clinch final 64 in national tournament or to be top 5 in the next season.
4. Ranked fifth last season, target to join the playoff or to be final 8 in the national tournament.
5. Participated playoff game(s), target to get into the playoff final and play against Big 8.
6~8. Participated playoff game(s), target to get into the playoff final and win the promotion.
Should the manager make such achievement, then we could give him, say expanding the arena by 500 seats, or better ranking to select the draftees.
