The Dallas Cowboys have looked as good as any team in the NFC through two games. The Miami Dolphins couldn’t have played any worse to start the 2019 NFL season. Put those two teams on the same field and you’ll get one of the largest betting lines in recent memory.

That will be the case in Week 3 when the Cowboys host the Dolphins at AT&T Stadium. Fewer than 24 hours after Dallas improved to 2-0 and Miami dropped to 0-2, the point spread has climbed up to 21 points in favor of the Cowboys, according to OddsShark.

The total for Sunday’s game is 47.5.

Miami hasn’t scored 47 points in their first two games. They haven’t even come close, losing 59-10 against the Baltimore Ravens in the opener and being shut out 43-0 by the New England Patriots in Week 2.

Both of those games were played in Miami. The Dolphins don’t figure to be very competitive when they visit Dallas, where the Cowboys beat the New York Giants 35-17 in Week 1.

The Cowboys didn’t have any trouble winning on the road against the Washington Redskins, defeating their NFC East rivals 31-21. Dallas led by at least two touchdowns for the final 25 minutes of the game.

Dallas’ plus-28 point differential is second-best among NFC teams. Miami has been outscored by 92 points. No other NFL team has worse than a minus-32 point differential.

Lamar Jackson and Tom Brady torched Miami’s defense in the first two games. Expect more of the same from Dak Prescott. The quarterback has been nearly perfect to start the season, completing 51 of 62 pass attempts for 674 yards and seven touchdowns. His one blemish was an interception in Washington.

Prescott has only been sacked once behind an offensive line that might be back to being the NFL’s best.

The Dolphins have surrendered an NFL-high 195.5 rushing yards per game. Ezekiel Elliott has led the league in rushing yards per game in each of his first three seasons.

Ryan Fitzpatrick and Josh Rosen might both see time under center. The two quarterbacks have combined to throw one touchdown and six interceptions in 2019.

The betting odds make it difficult to pick the Cowboys against the spread, no matter how poorly the Dolphins have played. Miami can’t be any worse in Week 3. Dallas will likely take their foot off the gas pedal in the fourth quarter, potentially leaving the possibility of a backdoor cover.

Dallas surrendered meaningless touchdowns in both Week 1 and Week 2 when the games were in hand, though they did cover the spread in both contests.

This is going to be a very one-sided affair. Dallas’ success under offensive coordinator Kellen Moore and the likelihood of garbage-time touchdowns might make the over the best bet in this game.

Prediction: Dallas over Miami, 34-17
