Avoid Discipline
The game randomly has a student act up and requires discipline. After each game, save your dynasty. Then, select the next game but make sure you have it checked as if you wish to play it, even if you are going to simulate it. If the discipline window appears, exit out and reload your dynasty. Go to that game again. Make sure you have the game checked to play so that the controller selection screen appears or else the CPU will take care of discipline, which is bad if you did not put any points into it. Then, exit out and simulate when the game is clear. With this, you can make any cupcake team a contender in no time.
