At the main menu, select "Features", "Create-A-Play", then "Create New Play". Create an "Offensive Run". Use the "Split Backs" formation. Select "Normal", and when it loads press R until it is over your Half Back. Change the type to "Runs". Change the play to "Toss L". Have your left wide receiver blocking, and the play is "Run Blk R". When you test out the play, make sure that you run along the sidelines and juke people out if needed. If you keep doing this, you should get easily score a touchdown with a few attempts.
