ASHBURN, Va. (AP) -- When Robert Kelley showed up a few pounds heavier after his red shirt year at Tulane, running backs coach David Johnson gave him a backpack with ''Fat Rob'' inscribed on it, and the nickname stuck.
More of a moniker among friends than anything else for several years, ''Fat Rob'' resurfaced when Kelley joined the Washington Redskins in training camp. The undrafted free agent is now going into his third game as the Redskins' starting running back Sunday night against the Green Bay Packers.
He earned the spot by being Positive Rob.
