It's going to be tough honestly. I seriously doubt he has any more games like he did tonight. No teams are as bad as the Bears.
Also, if he's anywhere close going into the last game against the Skins, they're going to absolutely stack the box to make sure he doesn't get it. They have nothing to play for, they won't care if we score on them through the air. But they will care strongly about being the team that gives up the 2,000 yards rushing, to a Cowboy no less.
I think he gets close, about 1,900 yards or so. Hope I'm wrong though.
