At 4-1, the Dallas Cowboys are off to one of the more impressive starts of any team in the NFL this season - especially considering the injury to quarterback Tony Romo during the preseason.
The Cowboys' offense has relied on a pair of rookies to carry them through the first five games, and quarterback Dak Prescott and running back Ezekiel Elliott are off to a historic start.
According the ESPN's Adam Caplan, the Cowboys are the first team in NFL history to have a rookie quarterback with at least 1,000 yards passing and a rookie running back with at least 500 yards after five games.
Prescott has thrown for 1,239 yards, four touchdowns and no interceptions on the season, and he has also completed 69 percent of his passes. Elliott has rushed 109 times for 546 yards and five touchdowns.
