Use FanDuel Promo Code on Chiefs-Giants on SNF

Here's our betting preview, NFL odds, and match info for Kansas at New York on SNF:

The Kansas City Chiefs will look to pick up their first win of the season when they battle the New York Giants on Sunday Night Football. The Chiefs are -6.5 point favorites to win this game on the road.

• NFL Sunday Night Football Week 3: Kansas City Chiefs at New York Giants
• Time: 8:20 p.m. EST
• Venue: MetLife Stadium in East Rutherford, NY
• Spread: Chiefs -6.5
• Total: 45.5
• Moneyline: Chiefs -295/Giants +235

The Chiefs lost to the Philadelphia Eagles in the Super Bowl last year, and they have started off this season poorly, going 0-2 with losses to the Eagles and the Los Angeles Chargers. Still, it’s the Chiefs. They have QB Patrick Mahomes and TE Travis Kelce, and you would be making a big mistake if you completely counted this team out of making the playoffs this season.

The Giants, meanwhile, look like they are a bad team that could fire HC Brian Daboll with another couple of losses. The Giants have lost to the Washington Commanders and Dallas Cowboys so far, and they figure to have another tough night on the field against the Chiefs.

The Chiefs won’t lose forever. This team is too talented, and they will win this game against the Giants on the road on Sunday night. Take the Chiefs to cover the -6.5 points on SNF.
