The Seattle Seahawks resume their pursuit of the No. 1 seed and home-field advantage in the NFC playoffs when they take on a desperate Los Angeles Rams team on Sunday Night Football at Los Angeles Memorial Coliseum. The Seahawks (10-2), who are looking to win their sixth straight game, are one of five teams that entered Week 14 with the best record in the NFL. But they're just 3-6 in their last nine meetings against the Rams. However, the Seahawks are 4-0 against the spread in their last four games. Meanwhile, the Rams (7-5) trail Minnesota by one game for the second and final Wild Card spot in the NFC. Kickoff is set for 8:20 p.m. ET. Seattle opened as a 2.5-point favorite in the Seahawks vs. Rams odds, but oddsmakers currently have Los Angeles as a one-point favorite. The over-under, or total number of points Vegas thinks will be scored, currently sits at 47.5. Before you make any Rams vs. Seahawks picks of your own, be sure to see the Sunday Night Football predictions from SportsLine's resident Rams expert, R.J. White

White has been SportsLine's top pro football analyst since the start of the 2017 season. Over that span, the CBS Sports NFL editor and nationally-recognized NFL Draft expert has gone 265-218 on NFL picks against-the-spread, returning $2,335 to $100 bettors. 

The stats guru, whose picks are coveted by fans everywhere, has hit it big in the world's most prestigious handicapping tournament -- the Westgate Las Vegas SuperContest -- twice in the past four years. In addition, he has had a particularly keen eye for the Rams. He has hit 30 of his last 43 picks involving Los Angeles. Anyone who has followed him is way up.

Now, White has zeroed in on Seahawks vs. Rams and locked in another confident against-the-spread pick. You can see it at SportsLine. Now, here are several NFL betting lines for Seahawks vs. Rams:

  • Seahawks vs. Rams spread: Los Angeles -1
  • Seahawks vs. Rams over-under: 47.5 points
  • Seahawks vs. Rams money line: Seattle -102, Los Angeles -118
  • Seattle: QB Russell Wilson leads the NFL with 26 touchdown passes
  • Los Angeles: DT Aaron Donald has 8.5 sacks in his last seven games

White knows that the Seahawks have been great at forcing turnovers. They have 27 takeaways this year, which ranks No. 3 in the league. In last week's 37-30 victory against Minnesota, Seattle forced three turnovers.

In addition, White has factored in that the Seahawks have been the NFL's best road team this season. The league's only undefeated team on the road, Seattle is 6-0 away from CenturyLink Field this year, including a 27-24 win at then-undefeated San Francisco in Week 10. The Seahawks have outscored opponents by an average of 26-20 when on the road this year. 

Even so, Seattle is no guarantee to win or cover the Seahawks vs. Rams spread on Sunday Night Football.

Los Angeles quarterback Jared Goff is coming off arguably his best game of the season. In last week's 34-7 victory over Arizona, Goff completed 32-of-43 attempts for 424 yards and two touchdowns. His completion percentage of 74.4 was a season-high and his 424 passing yards were the second most this season.

Defensive tackle Aaron Donald has been unblockable as of late. The reigning two-time NFL Defensive Player of the Year has 8.5 sacks over his last seven games. His 9.5 sacks on the season are the most by a defensive tackle.

White has analyzed this matchup from every angle and while we can tell you he's leaning under, he has discovered a crucial x-factor that makes one side of the spread a must-back. He's sharing it only at SportsLine.
