Best NFL betting sites for SNF: Packers vs Seahawks odds & preview Sunday's kickoff is set for 8:20 p.m. ET from Lumen Field in Seattle on NBC. As of Friday, the Packers were a consensus -2.5-point favorite and between -135 and -150 on the moneyline. The Seahawks were a consensus between +114 and +125 on the moneyline at the top sportsbooks. The total for Sunday night's game sits at over/under 46 points.  Both teams come into squarely in the NFC playoff picture. Green Bay is 9-4, three games behind the NFC North-leading Detroit Lions, but it is set for a wild card berth.  Seattle is 8-5 and leads the NFC West by 1/2 game.  Needless to say, a win would significantly boost each respective team's playoff hopes.  The Packers will rely once again on Josh Jacobs, who has been on a monster tear the last three weeks. If Green Bay is able to establish the run and consistently run the ball, that sets up quarterback Jordan Love to attack the Seattle defense through the air.  Geno Smith and the Seahawks offense have big-play capability. The key for both teams is holding onto the ball. The defense that forces the most turnovers and stops.
