Choose Rich Gannon as your QB, Pete Wheeler as your RB, and any wide receivers of your choice. On offense, select #1 and choose "Outside Handoff". Give the ball to Pete Wheeler and have him run it up the sidelines. Usually he will break away for a TD if you use it all four downs.
With two receivers on each side, make one do a slant route and one a fly. The one doing the slant will be wide open.
Choose a running play that has a receiver running a route to the opposite side of the field as the run. Hike the ball, then run backwards with the quarterback. He should not give the ball to the running back, but the running back will still make his run like a route. He will be uncovered. Wait for the running back to get down the field a gooddistance, then throw. If he catches the ball and is fast enough, it will be a touchdown. This is the best way to get yards catching for your custom to increase skill points.
To save during a game in season mode, call a timeout and go to "Change Playbook". When that screen appears, choose the "Save" button. A screen should appear with a list of saved games. Select to save again. You can now quit the game and return to that point at any time.
