When u click on schedule u have the option of setting your lineup for a game. You can set players at each of the 5 basketball positions either as your starter, backup or reserve. Your starters start the game, during the game your coach will sub your starters out for a rest and your backups take the court. Your reserve is there if anything happens to the starter and backup such as injury or fouling out. Collectively the Starter, Backup and Reserve are called your depth chart.
