He's a fairly good player (not top shelf, but a solid starter), but he's on a passing team with a bad offensive line.  This isn't exactly a shock to anyone who wasn't gulping the Kool Aid and drafting him in the 1st round.
		
		
	 
THIS.  He is not Jamal Charles, where he can overcome terrible line play with great skill and speed.  He is a plodder who needs lots of carries to produce.
		
 
		
	 
 
 He's definitely not a "plodder."  He lacks elite vision and instincts, but he's plenty fast and athletic IMO.  He's just a guy who will blast full speed into a couple of defenders and drag them for a 5 yard gain rather than making the subtle shift of direction to cut it back for 20+.
Comparing any RB outside of healthy Peterson or McFadden to Jamaal Charles an unfair starting point.  Charles has HOF level natural running ability.
		
 
		
	 
I don't think any of you have actually seen him play.
He has very good but not elite speed. LOL at calling him a plodder. Yea, when 6 guys are in the backfield.
He has very good, not elite vision.
He has excellent cutback ability and is a 1 cut back.
He has good, not great power, but is physical and doesn't back down.
He is an excellent receiver.
He plays behind a line with only 1 quality player in Tryon, the LT, none on the right side.
The offensive system is pass first.
In order to ensure the run is never successful, they usually run the ball out of big formations, essentially telegraphing that the play is a run.
It's hard to establish the run when you're either up by 35 or down by 35.
Did I mention Jason Garrett is his head coach?
