The High-Stakes Reality of the Divisional Round
Honestly, there’s nothing quite like the Divisional Round. It’s better than the Super Bowl in some ways because you get four high-level games in 48 hours without all the bloated halftime pageantry. Today, Saturday, January 17, 2026, we’ve got a massive doubleheader that’s basically a minefield for anybody looking at the nfl football lines for today without doing their homework.
We are looking at two No. 1 seeds—the Denver Broncos and the Seattle Seahawks—coming off their bye weeks to face battle-tested road warriors. The betting public usually hammers the home teams here. They think "rest equals success." But if you’ve been watching the movement at shops like DraftKings or FanDuel this morning, you’ll see the professional bettors are leaning a very different way.
Bills at Broncos: The Josh Allen Factor vs. Mile High Air
The afternoon starts at 4:30 p.m. ET on CBS with the Buffalo Bills heading into the thin air of Denver. The nfl football lines for today have the Broncos sitting as a narrow 1.5-point favorite. Some places opened this as a Pick ‘em, and it’s been jumping between -1 and -2 all week.
Why is it so close? Well, Buffalo is coming off a short week after playing Monday, but Josh Allen has basically turned into a postseason glitch. He’s got 79 career rushing touchdowns now—the most ever for a QB—and he’s already shredded Denver in the playoffs before.
Sean Payton is 17-3 straight up at home when he has more than nine days of rest. That is a staggering stat. But the Bills are 13-5 for a reason. James Cook has been a monster, racking up over 1,900 scrimmage yards this season. If Denver can’t keep him under 100 yards, the Broncos' pass rush won't matter because Allen will just keep them in third-and-short all day.
The total is sitting at 45.5. In Denver, in January, that feels high. The wind is projected to be a factor, and while everyone wants to see a shootout, these two defenses are top-ten units. Most of the early money (about 64%) is actually on the Bills to cover that +1.5. It feels like the world expects an "upset" that isn't really an upset.

49ers at Seahawks: A Rainy NFC West War
Then we move to the nightcap at 8:00 p.m. ET on FOX. This one is a classic. The San Francisco 49ers vs. the Seattle Seahawks at Lumen Field. The nfl football lines for today have Seattle as a 7-point favorite.
Seven points.
In a divisional rivalry game? That feels like bait.
Seattle is 14-3 and earned that No. 1 seed, but the Niners are the ultimate "zombie team." You think they’re dead, and then Sam Darnold finds another gear or Christian McCaffrey just decides to carry the ball 30 times. The Niners have been great against the spread this year, going 12-6.
The "sharps"—those professional bettors who move the markets—are all over San Francisco +7. Even though 70% of the public bets are coming in on Seattle to win, the line isn't moving to 7.5 or 8. That tells you the books are scared of the 49ers' side.

The weather in Seattle tonight looks like classic PNW gloom. Rain, 42 degrees, and a slick turf. That usually favors the team that can run the ball and play ugly. If the Niners can keep the Seahawks' offense off the field, that 7-point spread is going to look massive by the fourth quarter.
What the Numbers Actually Tell Us
When you're scanning nfl football lines for today, you have to look past the "Who will win?" and ask "How much will they win by?"
The Divisional Round has a weird history. Since 2005, home favorites coming off a bye are about 50% against the spread. The "rest" advantage is often offset by "rust." Denver hasn't played a meaningful snap in two weeks. Buffalo just played a high-intensity game five days ago.
Key Betting Metrics to Watch:
- The Bills' Short Week: History says teams on a 5-day turnaround struggle, but Buffalo is 4-1 in their last five such spots.
- The Seattle Home Field: Lumen Field is loud, but the 49ers have won there in two of the last three seasons.
- The Over/Under Trends: Both games today feature totals in the mid-40s. With the cold weather moving into both Denver and Seattle, the "Under" is getting a lot of late looks.
How to Handle These Lines Today
If you’re looking to get some skin in the game, don't just follow the "Green checks" on your betting app.
- Watch the 1.5 in Denver. If that line moves to 3, jump on the Bills immediately. If it drops to 1, the Broncos are the value play.
- The 7-point hook in Seattle. Seven is a "key number" in football. If you can find the Niners at +7.5, take it. If it’s at 6.5, stay away.
- Player Props over Spreads. Sometimes the game script is too messy. Look at Josh Allen's rushing yards or Kenneth Walker's receiving totals instead.
The playoffs are about variance. One muffed punt or one bad call from Carl Cheffers (who is officiating the Bills/Broncos game, by the way) can ruin a spread.

Actionable Strategy for Today's Games
Stop looking at the records and start looking at the matchups. Denver’s secondary is elite, but they struggle with "mobile" quarterbacks who break the pocket. Josh Allen is the definition of that problem.
In the night game, Seattle's offensive line has been shaky against interior pressure. If the 49ers can get to Geno Smith with just four pass rushers, it won't matter how loud the 12th Man screams.
To make the most of the nfl football lines for today, wait until about 30 minutes before kickoff. That’s when the "inactive" lists come out. If a key offensive lineman is out for Denver or Seattle, those lines will move fast. Be ready to move with them.
Check the wind speeds at Mile High right before the 4:30 p.m. ET kickoff. If it's over 15 mph, the "Under" becomes the smartest play on the board.
Enjoy the games. It's going to be a long, loud Saturday.
