Steven Jackson has scored only 20 touchdowns the last four years, even though he went over 1,000 rushing yards in all of those seasons. Nobody's ever done that before; normally when a back runs for a 1,000 yards, he also tends to wind up in the end zone more than occasionally.
Here's the list of the three-season guys. All of these players ran for 1,000-plus yards three years in a row. Of these running backs (and there's been 109 of them in the last 20 years), only a handful have scored under 20 touchdowns in those three seasons.
