When it comes to betting on Week 2 of the 2019 NFL season, it’s important to figure out what was real and what was an aberration in Week 1. That’s especially true for Sunday’s contest between the Dallas Cowboys and Washington Redskins.

Dallas is laying 4.5 points against Washington, according to the latest betting line at OddsShark. The Cowboys are road favorites after dominating the New York Giants at home in a 35-17 victory. The Redskins lost on the road to the Philadelphia Eagles 32-27, though they did cover the spread and make it a much more competitive game than many had predicted.

The game total is 46.5.

Even though they did it against a Giants’ team that has one of the NFL’s worst defenses, the Cowboys’ win is likely a sign of things to come. The Redskins should still be among the league’s worst teams, despite challenging the Eagles.

The Cowboys picked up where they left off last year, which saw them finish the regular season with seven wins in eight games. Dallas’ offense dramatically improved with the addition of Amari Cooper, and the unit could take another leap in 2019 with Kellen Moore as the offensive coordinator.

No, Dak Prescott won’t post a perfect passer rating for a second straight game, but the quarterback should have plenty of success. Dallas’ offensive line looked as good as ever in Week 1, giving Prescott time to pick apart New York’s weak secondary. Washington could suffer a similar fate after allowing Carson Wentz to post a 121.0 passer rating in the opener.

Case Keenum was one of the big surprises in Week 1. In the first half against the Eagles, he looked like the quarterback that led the Minnesota Vikings to the 2018 NFC Championship Game. Keenum finished the contest with 380 yards, three touchdowns and no interceptions.

Put Keenum at the top of the list of players that are unlikely to have a repeat performance in Week 2. The signal caller has a career passer rating of 85.2 in 58 games for a reason. The Denver Broncos replaced him with Joe Flacco after he had 18 touchdown passes and 15 interceptions in 2018. He could come crashing back to earth Sunday against one of the league’s top defenses.

Washington has lost five of their last six games against Dallas at home. The Cowboys are 6-3 against the spread in their last nine matchups with the Redskins, per OddsShark.

In four of their last five meetings, Dallas has beaten Washington by five points or more.

Since the start of the 2016 season, no NFC team has more regular-season wins than the Cowboys. Now that Cooper is on the team for a full season, it’s a safe bet that Dallas will be among the top teams in the conference.

This is probably the worst Redskins’ team that Prescott has faced since entering the league. He shouldn’t have much trouble improving his lifetime record against Washinton to 6-1.
