During Weeks 1-13, Dallas Cowboys rookie quarterback Dak Prescott posted a Total QBR of 85.0, the best mark in the NFL. But that plummeted to 22.1 against the New York Giants on Sunday night in a Week 14 loss, as he completed only 17 of 35 passes for 167 yards, one touchdown and two interceptions.

Was the rookie quarterback exposed in a way that will continue to be an issue, or can the Cowboys make some corrections and adjust the offensive call sheet to facilitate more production? Let's discuss three ways Prescott and the Cowboys can learn from the tape over the past two weeks to improve the offensive efficiency in Dallas.

Avoid locking in on Bryant

Since Dez Bryant returned in Week 8, he has seen 57 targets in the passing game, and he has produced 27 receptions for 494 yards (18.30 yards per catch) and four touchdowns. I understand why Prescott would want to get the ball out to Bryant. He's a true No. 1 with the speed, size and matchup ability to win inside and outside of the numbers.

Plus, in my opinion, Bryant is also the league's most dynamic weapon in the red zone. He's too physical for defensive backs at the point of attack.

But given Bryant's 47.4 percent catch rate since Week 8 and his average air yard per target of 15.39, the Cowboys' hyperefficient passing game that we saw earlier in the season has dropped off a bit with Prescott locking in on his No. 1. This showed up multiple times on the tape versus the Giants when Prescott had options open on much higher-percentage routes.

Take a look at this example:
