History of running back holdouts

Given the physical punishment associated with the position, running backs' shelf lives are often much shorter than other elite players' careers. So it's understandable that the Jacksonville Jaguars' Maurice Jones-Drew is hardly the first big-name running back to holdout while positioning himself for a new deal. But history shows that everyone -- from MJD himself, to the Jaguars and their fans, to fantasy football owners -- have reason to worry about MoJo's unexcused absence.
