The Facts: Karney agreed to a three-year, $3.6 million contract that includes $1.2 million in guarantees with the Rams, according to a source.

Diehards Line:The Rams have been struggling at that position since they released Madison Hedgecock in 2007. The signing of Karney gives St. Louis a chance to be more successful in two-back formations. The 5-11, 258-pound Karney had 46 career starts in five seasons with the Saints. Karney will be the blocking back for Rams halfback Steven Jackson.
