The Dallas Cowboys, already a historic 0-8 against the spread this season, are now listed as double-digit home underdogs for just the second time in the franchise's storied history in the Super Bowl era.
The Cowboys have been installed as 13.5-point home underdogs to the undefeated Pittsburgh Steelers on Sunday. The only time they have been less favored to win a game at home was in 1989, when they were listed as 14.5-point underdogs to the San Francisco 49ers. They lost that game 31-14.
Dallas is off to a 2-6 start this season and is the only team yet to cover the spread in any game. At 0-8 against the spread, the Cowboys are tied with the 1991 Cincinnati Bengals and 2003 Oakland Raiders for the worst ATS start in a single season in the Super Bowl era.
And the situation in Dallas could be getting tougher.
Veteran quarterback Andy Dalton will miss a second straight game, sources told ESPN's Todd Archer, after being placed on the reserve/COVID-19 list. Dalton, who took over the starting role after Dak Prescott was lost for the season with an ankle injury, suffered a concussion two weeks ago in a 25-3 loss to Washington.
Rookie Ben DiNucci started in the Cowboys' 23-9 loss to the Philadelphia Eagles on Sunday. DiNucci completed 21 of 40 passes for 180 yards, was sacked four times and lost two fumbles against the Eagles. A source told Archer that the plan is to work Garrett Gilbert and Cooper Rush this week with the first team, although DiNucci has not been ruled out oif starting.
Dallas hasn't been a 13.5-point or larger underdog in any game since 2001, when the Cowboys were 17-point underdogs to the Raiders.
While the Cowboys are stumbling, the Steelers are rolling. After winning at Baltimore on Sunday, Pittsburgh is now listed at 11-2 to win the Super Bowl, behind only the defending champion Kansas City Chiefs (7-2) at Caesars Sportsbook by William Hill U.S.
Dallas is now 150-1 to win the Super Bowl.
