Filling team needs
 

This is a particular problem in the early 1900s when teams have 22/23 players. With the AI doing the draft/trades, some teams end up with a lack of players at a position while others have an abundance at the same position. For example a couple teams might have only 1 active catcher on roster while others might have 5 or 6. Some teams might only have 3 pitchers while others have 7 or 8.
I wish the AI would do better either during the draft or through trades to make sure the positions on teams have adequate coverage.
