I don't see any good reason why the Cowboys would go from making McFadden a healthy scratch for over a quarter of the season, and then throw him into the lead back role. Morris doesn't play special teams, and clearly looked better in the preseason than DMac. It isn't as if they thought a handful of carries over the course of the first 5 games was going to seriously jeopardize McFadden's health so they didn't dress him. You always want to bring your top backup to the game on Sundays. Especially given the fact that Morris ripped off a 70 yard run recently as well. DMac missed almost all of last year, has been a scratch this year, looked stiff as a board in the preseason... I just don't see it.
