Select franchise mode, pick any team, and finish the season. Make sure you make the playoffs. Simulate or play all of the games until you get to the finals. Play the last game of the finals. You can play if desired, but if you think you are definitely going to win, go to the pause menu then choose "Quit" Then, go to simulate until the end. When the game is done, you will see a dancing cheerleader. Then your franchise's team's name will say "Champion" around it.
