There is a reason he is being compared to Marshall faulk by Stump Mitchell, Arians, Keim and Tom Moore.
Was Faulk limited because the defense knew of his abilities? He had a pretty good bunch of receivers around him in st louis - but he was still the focal point of the offense.
I really cannot understand how cardinal fans on this board are underselling DJ compared to the average nfl fan who is ranking him as the best fantasy RB. Chris Johnson is not half the back DJ is, if you don't see that than I don't think you know what a good running back looks like.
One thing I am sure of, they are not going to make chris johnson, who is 30 pounds lighter and all around inferior, the goal line back. They will give him some carries - I predict 5 a game, maybe not even that many because ellington is better than him when heathly - but his carries will not be at the goal line.
