"Since his high school days back in Attalla, Ala., Carnell Williams has been known as Cadillac because of his smooth running style. Still, if you referred to him as a Chevy now, Williams wouldn't be insulted.

"You know, a Chevy is not bad," he said, laughing. "A Chevy is a dependable car."

When the Rams called on him Sunday after running back Steven Jackson left early with a thigh injury, Williams proved to be dependable. And then some.

"That's not easy, to come in early in a game like that when Jack does down and (Williams is) asked to play as many snaps as he did," quarterback Sam Bradford said. "But I thought he did a great job. He ran hard, he had a great presence in the huddle, and I think the guys really kind of fed off him when he did come in there.""
