I agree that he runs too upright for my preferences in a running back and has shown to be injury prone, but he looks like a smart runner to me. I am not sure what you see that indicates he is not a smart runner. He has things to improve upon as most runners. Very few guys come into the league niced and polished.
His hands aren't that bad either. Better than Julius Jones, plus you have to consider who was throwing him the ball. Paul Thompson was not a good, accurate QB.
He will go top 5, so Dallas won't have a chance at him. They also don't have enough to trade up to get him. Shouldn't even think about that type of move anyway since they have several holes to fill and running back is the least of them.
