Philadelphia defensive coordinator Jim Johnson knows that it will be difficult to contain Adrian Peterson, the NFL's leading rusher. "He's one of the best I've ever seen," Johnson said. "A special guy. He's just a natural runner, a very gifted runner. He's got that Gale Sayers' feel about the game." The Eagles limited Peterson to 70 yards on 20 rushes in a 23-16 win over the Vikings last year, but the rookie did it against eight-man fronts, since the Vikings had virtually no passing attack to keep the defense honest. "He's a high-effort, talented, strong guy," Eagles' linebacker Chris Gocong said. "And really, I think everybody is going to have to be flying at him. There's not going to be a lot of times when the first guy makes the tackle. You've just got to slow him down and keep flying at him."
