The Cowboys released their first "unofficial" depth chart of the season Monday, and it includes RB Rico Dowdle as the backup to Tony Pollard. Malik Davis follows Dowdle, with Ronald Jones fourth and rookie Deuce Vaughn fifth. These preseason depth charts often hold things that aren't close to how the regular season works out. But the rest of this particular depth chart looks legit. We'll certainly be watching Dallas' backfield competition the rest of the way. There is no clear favorite for the No. 2 job -- and still the possibility that the Cowboys import a veteran.
