When I have my schedule made out and I make changes in the team manager, I have to erase my schedule to get the changes I made to the team to reflect on the game schedule. Shouldn't the team changes update automatically?

Changes you make to your team in Team Manager apply to the Roster. The Roster becomes the default Lineup for any game you create at the time you create it, but you would not want Roster changes to effect the lineups for games as each game could potentially have different players available to play. Rosters and Lineups are intentionally kept separate.

Many people do not pre-schedule the games... it only takes a few seconds to create a new game at game time, so many people wait until the day of the game to create the game so that the default Lineup that is created is based on the current Roster (in cases where teams change regularly with players coming to / leaving a team).
