There are some league rules to be aware of:
Park Restrictions: No park affects greater than +/- 2
Salary Cap: $15M per season, including signing bonus
Max Contract: 5 years/$75M total value, including signing bonus
Minor League Rosters: Minimum 23 players at each level, including minimum of 1 player for each defensive position.
Minimum wins: Any owner that fails to win at least 40 games in a season will be replaced. Any owner at or under a .250 winning percentage at the 81 game mark will receive a warning. If that owner remains at or under .250 at the 120 game mark, the commissioner will begin seeking a replacement owner and submit a ticket to have Admin review the situation. If Admin determines that the team is abandoned or that the owner is tanking, the commissioner will request that Admin replace the owner. Regardless of Admin's finding, the owner will be replaced at the end of the season if the team fails to win 40 or more games. We are starting with the 40 win threshold in season 19 and will likely increase that for season 20.
Any questions, just ask.
