A slimmed-down Rob Kelley is likely to remain Washington's top running back even though Adrian Peterson is joining the Redskins.
Amid four injuries in their backfield, the Redskins signed the 33-year-old four-time All-Pro running back on Monday. But Kelley, the former "Fat Rob" who lost weight and added speed to his repertoire, should still be considered the front-runner to start Week 1 at the Arizona Cardinals.
Washington lost second-round pick Derrius Guice to a season-ending torn ACL, won't have Samaje Perine and Byron Marshall for an extended period of time because of lower-leg injuries and waived undrafted free agent Martez Carter with an injury designation. That necessitated signing Peterson -a former standout at Oklahoma who played the majority of his career with the Vikings - and fellow running back De'Veon Smith, though coach Jay Gruden gave Kelley a vote of confidence on Sunday.
