Playing the 49ers hasn't been a good omen for NFL teams this season.
In addition to the 49ers' current nine-game winning streak, their opponents officially finished the 2022 NFL regular season 0-15 in their game the very next week.
The Las Vegas Raiders completed the feat when they lost 31-13 to the Kansas City Chiefs on Saturday at Allegiant Stadium.
While the stat might just be a coincidence, the 49ers' defense has taken a toll on teams, and coach Kyle Shanahan addressed the oddity before Week 16.
“It is a record we're aware of and it's one we think is pretty cool,” Shanahan said Dec. 22. “It's pretty cool stat. It could be a coincidence, but we like to think it’s not, so we'll take it that way.”
The 49ers wrap up the regular season against the Arizona Cardinals, but Kliff Kingsbury's squad isn't headed to the playoffs, so the streak won't continue next week when the postseason gets underway.
