Just how quickly can the mood surrounding an NFL team change? Just look at the Dallas Cowboys.
One year ago, the Cowboys were one of the league's most hyped contenders. They were coming off a 13-win season in which they won the NFC East in a cake walk. Quarterback Dak Prescott was the reigning Offensive Rookie of the Year, running back Ezekiel Elliott was the defending rushing champion, wide receiver Dez Bryant was a Pro Bowler after scoring eight touchdowns in 13 games and ironman tight end Jason Witten continued to be one of the game's top safety valves.
