http://espn.go.com/ always has rosters for just about every team and sport.
After you create a player, he is placed on the Free Agents list. Create all of the players you want to create first before you do anything else. Remember, these are players that are created OUTSIDE of a season game, so don't start a new season until after you have made your players. Now go into the Rosters section and you can manage your rosters the way you want. You can trade players on your team with players in the Free Agent list. When you have made all your trades and your roster is finished, you can then save your roster on the memory card. Now you start your new season and use the roster you saved. Your created players will be on the team, ready to play.
