Week 16 kicks off with one of the biggest games of the entire 2025 NFL season as the Los Angeles Rams visit the Seattle Seahawks on Thursday Night Football at Lumen Field. Both teams enter at 11–3 and are battling for first place in the NFC West, along with inside track for the top seed in the NFC.
Oddsmakers have made this essentially a coin flip. Current lines list the Rams as a slight road favorite at Rams -1, with a total of 44 points and moneyline prices around Rams -110 and Seahawks +100. The Rams are riding a strong December run and already own a narrow win over Seattle from earlier in the season, while the Seahawks have been almost unbeatable at home in prime time and have not allowed a 100-yard rusher in 23 consecutive games.
For new bettors, this sets up perfectly with the Caesars Sportsbook promo code ROTO20X, which gives you 20 separate 100% profit boosts after a simple qualifying wager. That means you can build an entire Week 16 card around Rams vs Seahawks and the rest of the NFL slate, each time doubling your potential winnings on eligible bets.
