Yeah, if they took an RB in the 3rd or 4th round there is zero guarantee that he would beat out McFadden or Randle, so it might just end up a wasted pick.2. There's two ways to look at the RB situation. The first is that they screwed up by not taking a guy in the draft to fill in his spot. This is the popular, and click generating, opinion. Negative news about the Cowboys is big business. The other is that the Cowboys felt they could move forward with what they had and get the same overall production they had last year using a rotation. I like this last approach but it could just as easily be wishful thinking. And we won't know until September.
If they need to find a guy before the season starts they can. Situations like Forsett with the Ravens happens every year - grab some guy off the scrap heap and he rushes for 1400 yards.
