Evan Engram might want to remind his Broncos teammates what happened in Denver on Oct. 15, 2017.

Engram then was a rookie tight end with the New York Giants. They were 0-5 and a 13.5-point underdog when they came to then-named Sports Authority Field to face the 3-1 Broncos on “Sunday Night Football.” The Giants, on their way to a 3-13 season, throttled Denver 23-10, then coached by Vance Joseph.

Engram is in first Denver season and Joseph, after being fired as head coach following the 2018 campaign, is in his third year as Broncos defensive coordinator. And coming in for “Thursday Night Football” at Empower Field are the 2-6 Las Vegas Raiders, a 10.5-point underdog against the 7-2 Broncos.

“They’re still a good team,’’ Engram said of the Raiders. “They’ve just had a couple of bad breaks. They’re going be hungry on Thursday night. … I’ve been on that team that has nothing to lose. So you kind of play with a little more freedom when you come in with no fear of losing. We can’t underestimate anybody no matter what their record is, but definitely those teams can be dangerous.”

Engram was dangerous in that game eight years ago. He caught five passes for 82 yards, including a 10-yard touchdown reception that put the Giants up 10-0 in the second quarter.

According to ProFootballReference.com, that Giants win remains tied for the second-biggest upset of the Broncos. The only one bigger was the Oakland Raiders being a 14-point underdog at Denver in 2009 and winning 20-19.

Broncos coach Sean Payton has been stressing to his players they can’t take the Raiders lightly. They claim to be listening.

Denver nose tackle D.J. Jones was with San Francisco from 2017-21, including when they went 6-10 and 4-12 in his first two seasons. Three times in those seasons, they almost pulled off huge upsets. In 2017, they lost 12-9 as a 13.5-point underdog at Seattle and 26-24 at Washington as a 12-point underdog. In 2018, they lost 29-27 on the road against the Los Angeles Chargers, a 10.5-point favorite.

“Those are the most dangerous teams to play,’’ Jones said of facing the Raiders. “They don’t have anything to lose, so we got to come in with our ‘A’ game. My first couple of years in San Francisco, we were like the underdog almost every game, so we played like we had nothing to lose.”

The Raiders won their opener 20-13 at New England but have dropped six of their last seven games. Their only other win was 20-10 over hapless Tennessee. While they have been crushed by AFC heavweights Indianapolis 40-6 and Kansas City 31-0, they did at least play well against playoff contenders Chicago, losing 25-24, and Jacksonville, falling 30-29 in overtime Sunday.

Raiders quarterback Geno Smith has been throwing the ball all over the place and has 11 interceptions, tied for the most in the NFL. On Tuesday, the Raiders traded disgruntled wide receiver Jakobi Meyer to the Jaguars for fourth- and sixth-round draft picks, so they will come to Denver without one of their weapons.

But the Raiders do have star tight end Brock Bowers, who caught 12 passes for 127 yards and three touchdowns against the Jaguars and was called “special” by Joseph. And they are coached by Pete Carroll, who once led Seattle to two Super Bowls, including a 43-8 thrashing of the Broncos in February 2014.

“He is someone you know will get a real well-coached team,’’ Payton said.

With that in mind, Broncos wide receiver Troy Franklin wonders what the Raiders might have in store Thursday.

“They’re got nothing to lose,’’ said Franklin, continuing with the popular description the Broncos have had this week for the Raiders. “So they’re probably going to come out with guns blazing, trick plays, all that good stuff. So we just got to be aware and stay alert.”

The Broncos have had some scares this season in games in which they were a touchdown-or-more favorite. As a 7-point favorite against the New York Jets in London on Oct. 12, they fell behind in the fourth quarter before winning 13-11 on a late Wil Lutz field goal. As a 7.5-point favorite against the Giants at home Oct. 19, they trailed 19-0 and 26-8 in the fourth quarter before a 33-point quarter gave them a 33-32 win.

In the last 11 seasons, the Broncos never have been favored by as much as they were on Oct. 15, 2017. And Engram and the Giants pulled off a stunning upset.

Now Engram is on the other side of a game in Denver with a lopsided point spread. He would be wise to talk to his teammates about what happened eight years ago.
