I found this to be the easiest way. Set up 1 min quarters with a team with good kick returners like the Bears and make sure to have unlimited rewinds. For AI settings, MAKE SURE to give the CPU great offensive stats all around and bad defensive stats. Also make sure that on defense you call a bad play like a punt block or field goal block this way the quarterback will throw it. That way when they score afterwards you will have a chance at a kickoff for a touchdown, just make sure it is the same player twice when you are doing it. The other touchdown can be gotten either at start of game or second half when you get the ball. If you fail twice with rewind, just keep making sure they score and you'll have more chances.
