How does the league manager in fantasy football leagues make changes?

In fantasy football leagues, the league manager can make changes by accessing the league settings through the platform hosting the league, such as ESPN or Yahoo. They have the authority to adjust rules, scoring systems, trade approvals, and roster limits, as well as manage the draft process. Additionally, league managers can address any disputes or issues that arise, ensuring fair play and adherence to league rules. Changes are typically communicated to all league members to keep everyone informed.
