The easiest way is to use two controllers set at 1 minute quarters (or however long you think it might take). If the opposing team has the ball, simply punt it back to you. Set their defense to “Field Goal Block” and have your receivers run a straight route every time. Run up the score.
Or, if you have one controller, turn offsides off and keep sacking the QB when you are on defense, forcing the punt. That way you are free to score as much as you like and the CPU team won’t. Make sure you set the quarter lengths to the appropriate time to get 59+ points.
