Last year it was Mark Ingram; this year the St. Louis Rams—for whom 2012 NFL Mock Draft types have helpfully restarted Steven Jackson's biological clock—are supposed to be interested in Alabama running back Trent Richardson. This makes sense if you're exclusively considering the Rams' needs at running back; Jackson isn't getting any younger, and a solid backup could help him last longer even as Richardson becomes the next great Rams feature back.
But here's the thing: The Rams had an outstanding running back last year, and they still went 2-14. Two outstanding running backs on a team that has needs almost everywhere else aren't going to pull this team over .500 by their simple devotion to Playing Really Hard and Rough and Tumbling and all that—it just can't be done anymore.
At some point the Rams are going to need a new running back. We should probably wait until they aren't the worst team in football with the running back we hope Trent Richardson could someday become.
