That is one mindset, to assume some one SHOULD'VE gained those yards if he's healthy. Another mindset, is that you can't award credit to someone for something he hasn't accomplished. There is no way to know what Dak WOULD'VE had 4000K if he hadn't been injured. Maybe he COULD'VE, but I'm not into playing that kind of game. Like I said, Romo and Dak's statistics look very similar here, yet I'm not going to play the SHOULD'VE, COULD'VE, WOULD'VE game for him. You think Dak is going to get 4K yards this seasons?
