Good dynasty football managers will tell you that a working knowledge of NFL runningback depth charts is essential. Many NFL teams like to stash one high potential player either on their practice squad, or 3rd on the depth chart. This player typically has a chance to be 3 down explosive runner if they can overcome the issues that have put them in the position to be buried on the depth chart. Some have significant fumbling problems, others cannot pick up a blitz, and another common dilemma is lack of maturity. I like to fill my roster with these players. I do not have to invest much to acquire them and they could pay huge dividends. If they do not work out, just drop them and pick up the next one. Here are a few that I am looking to acquire (or already have).
