Barry Sanders said Chris Johnson could be the first running back with two 2,000 yard seasons. "It will be tough to do it again, but yeah, he can be the first guy,'' Sanders said. "This is only his third year, so if he stays healthy, with his ability he could definitely do it again. ? "He is fast, but what I like about him is he looks like one of those track guys that actually knows how to run the ball and has good vision and patience. He is not just running at top speed. He knows when to use his speed, and he has some power and toughness, too.'' Sanders hesitated to call Johnson the best NFL back. "Obviously he had the most surprising year," he said, "but I don't know if he is the best pure runner."
