"The season is halfway done, and tight end Jason Witten said it is time for the Dallas Cowboys to start rolling.

"There comes a point in every season for every team that you start to separate yourself, and you see the league do that every year," Witten said. "For us, we've had some tough losses to bear, obviously some big wins, but we're at that point where we need to stack them up."

The schedule favors the Cowboys. While this week's opponent, Buffalo, has a winning record, the next three teams -- Washington, Miami and Arizona -- do not.

The Cowboys are coming off a split against teams with losing records, a loss at Philadelphia and a win against Seattle."
