MJ Challenge
For the MJ challenge parts where you need to limit Dominique Wilkins and Clyde Drexler's scoring, go to 'Rosters' and simply edit their stats and that will severely limit their scoring. Also, if you need help with the rebounding portions, go to 'Rosters' and edit the Michael Jordan you will be using and make him 7'6". This helps immensely. After you are done you can simply choose the 'Reset Rosters' option and all will be fixed.
