First, all you have to do is find one of your most valuable players after week 17 in franchise mode, and make sure he did not make the pro bowl. Trade him for a 1st and 2nd pick in next years draft. Then edit that same player you traded to where he has a different position, such as a defensive end made into a left tackle. This hint works best for running backs, offensive linemen, defensive linemen, and free or strong safeties with low catching, such as 80 or less. Try to stay away from using a wide receiver because of their catching. I personally believe the best to use is a linebacker because they get so good so quick, and you are allowed to change them into a running back therefore their break tackle and carring should be some what low.
