With a few weeks of the NFL season remaining, every game is crucial for playoff-contending teams.

Tonight's matchup will feature a battle for the NFC West and NFC overall between the Los Angeles Rams (11-3, 5-2 away) and the Seattle Seahawks (11-3, 5-2 home)

Featuring two top quarterbacks, Matt Stafford (-260) is the MVP front-runner, while Sam Darnold is respectfully a long shot to win the award at +100000 odds. Either way, this should be a top clash between two of the top quarterbacks this season.

While the Rams are the current top dogs of the NFC, the Seahawks trail behind for the fifth spot in the conference. According to NFL stats, Seattle has a 99% probability to make the playoffs, win or lose. However, tonight will be a fight for the NFC West crown.

The favorite to win Super Bowl LX (+370) and the NFC (+195), the Rams are also favored to win the NFC West (-145). Trailing behind are the Seahawks to win the division (+200 odds), and Seattle has the second-best odds to win the NFC (+380). While the books favor the Rams, Seattle can strike while the iron's hot!

NFC West: Who Will Win the Division—Rams or Seahawks?

Winners of four-straight outings, the Seahawks are slim 1.5-point spread and -124 moneyline favorites. After winning eight of their last 10 games, they face a Rams squad that has won two straight and eight of its last 10.

On paper, both squads are evenly matched. Additionally, tonight's matchup will highlight the Rams' No.1 offense against a top Seahawks defense. Cooper Kupp and Colby Parkinson will once again face their former teams.

With the division on the line, the Rams are 7-3 against the Rams over their last 10 meetings, and got the best of Seattle 21-19 in mid-November. Perhaps Sam Darnold will not see ghosts and throw four interceptions. In fact, he's been one of the most underrated quarterbacks this NFL season.

Tonight, the Rams are likely to roll without wide receiver Davanta Adams (Hamstring), while top offensive lineman Charles Cross has been ruled out on Thursday. Will the Rams remain No.1, or will the Seahawks dethrone them?

NFL Predictions for Thursday, December 18, Week 16: Rams vs Seahawks

NFL Player Prop Bets Tonight: Sam Darnold

2025-2026 Season Stats

GP: 14 | CMP: 263 | Attempts: 390 | Passing Yards: 3,433 | Avg.: 8.8 | Passing TD: 22 | Int: 11 |Pass Long: 67

• 230+ Passing Yards (+103 DraftKings)

My first-best bet for tonight, I placed one unit on Seahawks quarterback Sam Darnold to record 230+ passing yards.

This is a great spot for Darnold, whose current over/under passing yards prop line is set at 223.5.  For 6.5 yards more, I'll gladly take this player prop at plus money (+103 odds).

There's no denying the Seahawks have been a surprise team of the year, boasting the eighth-best offense in the NFL, and ranking second in offensive pass DVOA. This is primarily due to the absurd connection between Darnold and star receiver Jaxon Smith-Njigba.

Darnold, rightfully so, earned himself a payday after one several successful season in Minnesota. Although a long shot for NFL MVP (+100000), he respectfully remains in conversation. Ranked second in success rate among NFL quarterbacks (52 %), Darnold cracks outside the top five in pass yards (3,433) and pass EPA (72.9). Through 14 games, he's averaged 245.2 passing yards per game.

Sam Darnold In NFL MVP Conversations?

It's clear that Seattle head coach Mike Macdonald is sticking with a running back committee featuring Zach Charbonnet and Kenneth Walker III. However, I truly don't trust the Seahawks' run game, considering they average just 113 rushing yards per game, and rank No. 19 in offensive rush DVOA. After all, the Rams rank fourth overall against the run.

Sixth among NFL quarterbacks in pass yards, Darnold has been on a tear as of late. Soaring over this player prop bet in two straight games, we recently saw Darnold torch the Falcons and Vikings secondaries for 271 and 249 passing yards. With the state of the run game, he's tallied back-to-back 30+ pass attempts.

Committed to a pass-heavy offense, not only has Darnold cleared this line in four of the last five games, but he's also averaging 234.2 passing yards per game over that span.

The Seahawks weren't playing around when they traded for wide receiver Rashid Shaheed at the deadline. Now they arguably have one of the strongest wide-receiver corps with Smith-Njigba, Cooper Kupp, and now Shaheed.

While the Rams have a top defense, they've been forgiving against the pass. Not only do they allow the ninth-most passing yards to quarterbacks, but Jared Goff (Lions) and Jacoby Brissett (Cardinals) recently threw for 338 and 271 passing yards, recently.  This season, we've seen quarterbacks dominate LA, such as Mac Jones (319, 342 passing yards), Trevor Lawrence (296 passing yards), and Daniel Jones (262 passing yards) soar over this line.

Final Rams vs Seahawks NFL betting prediction: Sam Darnold 230+ Passing Yards (+103 DraftKings)

Despite throwing for four touchdowns against the Rams in November, Darnold managed to throw for 279 yards, completing 29 of 44 passes.

Overall, this season, Darnold has thrown for nearly 800 yards against top 10 pass defenses.

• Is tonight the night Sam Darnold finally beats the Rams? I'm taking him to record 230+ passing yards for plus odds here. Half of this line can come from Smith-Njigba alone. Clearing 230+ passing yards in nine games this season, I'm backing Darnold tonight. Throwing for 279s despite four interceptions in their first matchup... is quite impressive. 

NFL Player Prop Bets Tonight: Jason Myers

2025-2026 Season Stats

GP: 14 | FG: 37-42 | FG %: 88 | 20-29: 5-5 | 30-39: 12-13 | 40-49: 11-12 | 50+: 9-12 | Long: 57

• OVER 7.5 Kicking Points (-115 DraftKings)

My second-best bet for tonight, I placed one unit on Seahawks kicker Jason Myers to record over 7.5 kicking points.

It's rare I bet on special teams, but I couldn't pass this one up, especially for the value. Myers leads all NFL kickers with 37 field goals made this season, and while there's been some misses (88.1 % FG percentage), he has a great matchup tonight.

With 100 percent on extra-point attempts, Myers is one of the most efficient long-range kickers in the game. 9-12 from 50+ yards plus, it's hard to forget his performance against the Rams in November.

Yes, Sam Darnold was seeing ghosts, throwing four interceptions, yet the Seahawks managed to just by just two points. We can look at Myers, who recorded 13 points, on four of five field goals. 1-2 from 50+, it was Myers who kept the Seahawks in the game.

Why Special Teams Can Matter Thursday Night

I'm not saying Darnold will have a repeat performance, especially given the way he's playing as of late. As mentioned in my previous article, this is a Rams team that has recently allowed 41 and 31 points to the Detroit Lions and Carolina Panthers over the last three weeks.

While Seattle boasts a fourth-down conversion rate above 70%, they are one of the least efficient teams on third down (38%). Leading the team in field goal attempts (42) and field goals made (37), I'm confident in this player prop tonight.

Let's face it—we are talking about a kicker that averages 4.3 field goals made on 4.3 field goal attempts per game. A top-ten team in offensive DVOA, this  Seattle offense has shown flashes of potency.

Am I really going to fade a kicker who's soared over this prop line in nine straight games? Averaging 12.1 kicking points over that span, can we talk about last week?

Final Rams vs Seahawks NFL betting prediction: Jason Myers OVER 7.5 Kicking Points (-115 DraftKings)

In the Seahawks' week 15 41-34 victory over the Detroit Lions, Myers put up 18 kicking points, hitting 6/6 of his field goals. Recording 16 points against the Rams in November, I feel the books are sleeping on this line!

• For those reasons, I'm taking Jason Myers to record over 7.5 kicking points tonight. It's expected to be a close matchup; it could come down to one kick.

Team Total Prop: Rams vs Seahawks

• Los Angeles Rams OVER 20.5 Total Points (-110 DraftKings)

My third-best bet for today, I placed one unit on the LA Rams to record over 20.5 total points.

Maybe last week was a fluke, but I was confused that the top offense in the NFL could barely score 18 points against Phillip Rivers and the Indianapolis Colts.

Let's let that slide, because that one matchup doesn't showcase who the Rams have been the entire season. A complete powerhouse, the Rams boast the No. 1 offensive DVOA, averaging 383.6 yards and 30 points per game. Led by MVP front-runner Matthew Stafford, there are few holes in this offense.

It's likely the Rams will be without receiver Davante Adams, which will put a dent in the offense. Even so, LA has the best quarterbacks in the league in Matt Stafford, and Sean McVay is leaning towards a 1-2 punch run committee between Kyren Williams and Blake Corum.

Let's not forget about wideout Puka Nacua, who's had a breakout year with 1,367 receiving yards and six touchdowns. Colby Parkinson, Konata Mumpfield, Jordan Whittington, and Terrance Ferguson are all viable options for Stafford tonight.

Rams vs Seahawks: No.1 Offense vs. No. 1 Defense

Scoring back-to-back 40+ points, the Rams poured 41 on the Lions and 45 on the Arizona Cardinals. Averaging 37 points over the last four games, we are talking about a team that's scored a low of 14 points against the Texans in week 1.

In fact, the Rams have scored over 20.5 points in 12 of 14 games this season. We've seen them score 14 points against a stingy Texans defense, but we've also seen them dominate the Saints and 49ers, scoring 34 and 42 points.

Yes, the Seahawks boast the best defense in the NFL, limiting opponents to 17.3 points per game and 283 total yards per game. Allowing less than 200 passing yards per game, they allow the third-fewest rushing yards per game (91.6).

Defeating Seattle 21-19 earlier this season, these two squads have familiarity with each other. While Stafford threw for just 130 yards, it was efficient enough for two touchdowns. Furthermore, Williams handled the rest on the ground.

This Seahawks' defense is no joke. Although barely defeating Phillip Rivers, they held the Colts to 18 points last week. Not to mention, they shut out the Vikings 26-0, and torched the Falcons, 37-9.  The last time they allowed 20+ points came against the Titans four weeks ago. This season, they've let just three teams soar over that line.

Final Rams vs Seahawks NFL betting prediction: Los Angeles Rams OVER 20.5 Points (-110 DraftKings)

With the total set at 42.5 points, this is a perfect number for the Rams to settle in at. While Seattle has an elite defense, it's not exactly the legend of boom. While high winds can certainly affect the outcome tonight, 2o.5 points seems low for a team that puts up 30+ points per game.

• I'm taking the Rams to record over 20.5 points. It should be a low-scoring affair and overall a tight matchup.
