The Dallas Cowboys are the defending NFC East division champions. It is well known that there has not been a repeat divisional winner since the Philadelphia Eagles won four in a row from 2001-04.
The early season predictions anticipated that the NFC East trend would continue. A quick google search found preseason predictions from ESPN, The Sporting News, Sports Illustrated, CBS, The Ringer, Bleacher Report, and NFL.com.
The Cowboys were picked to win the Division only seven of the forty forecasts representing 17.5 percent of the picks. The remaining thirty-three were all in on the Eagles.
