Five takeaways from the Dallas Cowboys' 30-16 win Sunday at Green Bay:

1) Is the Prescott-Romo debate over?

Rookie quarterback Dak Prescott engineered his most impressive feat yet: a Cowboys win at Lambeau Field over the Packers.

Anyone who still wanted Tony Romo to get his job back when he's healthy might have shifted gears after watching this one.

Despite throwing his first interception and losing a fumble, Prescott overshadowed Packers quarterback Aaron Rodgers in Rodgers' backyard.

His statement moment came in the final two minutes of the first half. Prescott led the Cowboys on a five-play, 97-yard touchdown drive in only 33 seconds with no timeouts right before halftime to give Dallas a 17-6 lead. A drive that impressive as a rookie could have implications beyond Sunday's game as the Cowboys decide whether to bring back Romo.

Prescott never blinked -- even after his two turnovers -- putting Green Bay away in the fourth quarter. His drive ended like many of Prescott's do: with a touchdown pass to Cole Beasley.

Prescott finished 18 of 27 for 247 yards and three touchdowns. He threw one pick and lost a fumble as well, finishing with a 117.4 QB rating.

2) Zeke, Cowboys OL trumps Green Bay run defense

The Cowboys played the league's top rushing defense Sunday in the Packers. And not much changed for Dallas.

The Cowboys continued to dominate on the ground. Running back Ezekiel Elliott rushed for more than 100 yards for a fourth consecutive game, the first rookie to accomplish that feat in franchise history.

What's more: Elliott finished with more than 130 rushing yards for a fourth consecutive game, the first time a rookie has ever accomplished that in NFL history. Elliott finished with 157 rushing yards on 28 carries.

Coming into Sunday, the Packers had allowed an NFL-best 42.8 rushing yards per game and had only given up two runs of more than 10 yards. Elliott had runs of 29 and 25 yards among several other big gains.

The Cowboys' offensive line was boosted by left tackle Tyron Smith, who played Sunday despite missing practice time this week with a sore back.

3) Well, it is Sunday

Cowboys safety Barry Church intercepted an Aaron Rodgers pass on the Packers' opening possession of the second half.

It was a huge takeaway that helped the Cowboys keep momentum after they drove the length of the field to end the first half with a 17-6 lead.

Church dropped down in coverage, and Rodgers threw the ball right to him on the left side.

The Cowboys converted the Church interception into a field goal for a 20-6 lead.

The Cowboys defense played well again, finishing with four takeaways on the road.

Church has had a good season so far. That's big for him considering he'll be an unrestricted free agent in the offseason.

4) DL David Irving comes up big in red zone

Cowboys defensive lineman David Irving was clutch with the Packers in the red zone on back-to-back drives in the second half.

With Green Bay down by two touchdowns in the third quarter and about to score, Irving knocked the ball out of Aaron Rodgers' hands on a quarterback draw inside the 5-yard line and then recovered the fumble.

Irving, who missed last week's game with a concussion, came back with another huge play on the Packers' ensuing drive in the red zone. Following Dak Prescott's first career interception, the Packers had 3rd-and-10 from the Cowboys' 16-yard line. Irving tipped Rodgers' pass away at the line of scrimmage to force the Packers to settle for a field goal that cut the lead to 20-9.

Late in the game, Irving forced yet another fumble by stripping the football from Green Bay's Ty Montgomery. Ryan Davis recovered for the Cowboys to put the game away.

5) Remember that 2014 win at Seattle?

The Cowboys won at Lambeau Field for only the second time ever, showing the NFL that Dallas is for real.

It was a statement victory, reminiscent of a trip northwest during the 12-4 campaign in 2014.

The Cowboys were also 4-1 then, when they traveled to play at Seattle in a game many thought they wouldn't win. They beat the Seahawks, 30-23.

But Sunday's win at Lambeau Field was different. The Cowboys just destroyed the Packers at Lambeau with rookies starting at QB and running back. The Cowboys made mistakes -- Prescott had his first interception and lost a fumble -- and it didn't even matter.

The Cowboys' bye comes at a bad time with Dallas rolling right now.
