Richardson was the next to last pick of the draft out of Abilene Christian and at 196 pounds is 40 pounds lighter than Jackson. He's been a lot more than a change of pace back, running ahead of second-rounder Isaiah Pead since the preseason.
Richardson has 119 yards rushing, only 21 yards behind Jackson, with a 5.7-yard average. Jackson was held to 29 yards on 11 carries last week in a 23-6 loss at Chicago and his 3.4-yard average per carry by far the worst of his career.
