The Cowboys had quite an offense in 2016, when Dak Prescott took the Offensive Rookie of the Year Award after posting the third-best passer rating and total QBR behind Matt Ryan and Tom Brady, Ezekiel Elliott led the NFL in rushing, and the O-line won the inaugural Offensive Line of the Year Award.
The 2016 Cowboys scored 421 points, the 10th-most in franchise history, for a cool 26.3 points per game average. That wasn't quite enough to reach the 30-point per game threshold, but it was the fifth-best total in the league last year, and a little over a field goal shy of that 30-point threshold.
