If there were holes he wasn't hitting or the fact that the ravens were 3 yards in the backfield on every run play, then I would agree with the OP. Being that's not the case, I will say that Deangelo is still the best all around back on the team. Give him some holes and he runs better.
Gotta disagree. If he can stay healthy, I think Stew is the best RB on the team, because a bruiser like that will get you yards even with a bad O-line. He also has the explosion and the speed of D-Will.
