League setup then edit league structure and you can import just one team
Importing Historical Teams
You can also use this page to import an entire historical team, such as the 1967 Red Sox. To do this, just click the
Import Hist. Team button in the same row as the division you wish to hold the imported team. You will be prompted to find the historical database you wish to use. The default database is in
data/stats/historical_database.odb within your OOTP installation. You will then be presented with historical import options including a list of teams.
If you change the Season Year value, you must hit
Refresh Teams List to get the set of teams from that year. Otherwise, the options on this screen are the same as those described in the
Adding Historical Leagues page. When you are done tweaking settings, click on the
Import Team button to proceed.
