Visit a NBA fantasy basketball website. The website will allow you to create a fantasy team and create a league with other people. Yahoo Fantasy Sports, ESPN Fantas, and NBA Fantasy Basketball are three free online services with which people can create a fantasy team.
Select the "Create" or "Join" button located on your homepage of choice. If required, create an account on the following page by filling in the requested information. Select "Register" to register with the fantasy team service and start the league.
Enter the name of the league you wish to join if you selected the "Join" option. Click "Enter League" or something similar next to the league to join the league. If you're creating a league, enter the name of your league, set rules and input other other required information. Select the "Invite" option to invite other people into the league.
Follow the rules as listed on the fantasy basketball service to learn when you can draft NBA players to your fantasy team. Once it is time for the draft, select the NBA players that will play on your roster. After adding the players, set the starting lineups, the bench and reserve players that will gain points for you during the NBA season.
