In the last week of the NFL regular season, both the Raiders and Chargers were fighting for a playoff spot. But due to a quirk in the NFL playoff standings, a one-of-a-kind scenario emerged: if the game ended in a tie, both teams would clinch a postseason birth.

Theoretically, if both teams elected to kneel down on every play of the game, they could guarantee a playoff spot for their franchise. If not, the team risked not making the postseason at all.

This potential tie scenario led thousands of bettors to wager on the long-shot possibility of a tie game in the NFL, something that happens less than 1% of the time.

To tie a game in the NFL, a game needs to go into overtime and at the end of the 10-minute overtime period, the score must remain tied.

Fellow legal U.S. sports betting operator, PointsBet, also stated that liability on a potential tie in the Raiders-Chargers game was over a million dollars for their sportsbook.

“I know it was unintentional,” DraftKings sportsbook director Johnny Avello told ESPN after the game. “But Steven Spielberg couldn’t have written and directed a better script.”
