NFL Week 17 betting preview

The New York Giants play the Las Vegas Raiders in a matchup that is essentially the battle for the No. 1 overall pick as the only two teams left with only two wins this season. Jaxson Dart will make his 11th start for the Giants, and his rookie season has been a mixed bag of highs and lows. Meanwhile, veteran Geno Smith starts for the Raiders against the Giants, where Smith played one NFL season and infamously was the quarterback inserted to end Eli Manning's 210-game starting streak. Smith resurrected his career afterward, but he and the entire Raiders team have struggled this year. Brock Bowers and Maxx Crosby are both out for the Raiders. Both teams enter on a nine-game losing streak, and the Giants are three-point favorites in the latest Week 17 NFL odds at Fanatics Sportsbook for this 4:05 p.m. ET start.

Shortly after they begin, the Buffalo Bills host the Philadelphia Eagles in a potential Super Bowl preview. Josh Allen has battled a foot injury, but he is good to play for Sunday for Buffalo, which has won four straight games. The Bills are averaging 30.8 ppg over their last four games, while the Eagles have scored at least 29 points in back-to-back games. Each team is filled with offensive firepower, such as Allen, James Cook, Jalen Hurts, Saquon Barkley and A.J. Brown. The Bills are favored by three points at Fanatics for this 4:25 p.m. ET start.

The San Francisco 49ers control their fate for the No. 1 seed in the NFC, securing the top spot if they win each of their final two games. Both come against teams playing in the postseason, starting with the Bears on Sunday Night Football. After dropping their first two games of the season, the Bears are 11-2 over their last 13 games and are coming off an improbable comeback victory over the Packers in overtime last week. The Bears also remain in the chase for the No. 1 seed in the NFC. The 49ers are 3.5-point favorites at Fanatics for Sunday Night Football. Click here to sign up for Fanatics Sportsbook to bet and get up to $2,000 in No Sweat Bets in FanCash at Fanatics:
