Everything clicked for Dallas last season, pounding away at opponents with DeMarco Murray behind the league's grittiest offensive line. Murray is gone -- to Philly, of all places -- leaving the Cowboys to talk up a declining Darren McFadden as a secret weapon. We still see the 'Boys as a dark horse to trade for Adrian Peterson, but reality suggests the team will be forced to lean on a rookie runner. Dallas -- no fluke last season -- will compete into December, but Chip Kelly's revamped Eagles will own the last laugh.
