Entering the 2025 NFL playoffs, no team had more against-the-spread wins than the Chargers, while no postseason team had fewer ATS wins than the Texans. Then, Houston went out and won outright as underdogs during Wild Card Weekend. Does that suddenly make the Texans ones to back in Divisional Round NFL best bets? Houston is an 8.5-point underdog to Kansas City, per the latest NFL odds, while the only larger Divisional Round NFL spread has the Lions favored by 9.5 points over the Commanders. Road teams went just 1-5 against the spread last week, so should you jump on the home teams in a Divisional Round NFL parlay?

Which trends and betting lines could help with your NFL betting strategy? Before you make any Divisional Round NFL picks or parlays, you need to see what SportsLine senior analyst Larry Hartstein has to say. 

A former lead writer for Covers and The Linemakers, Hartstein combines a vast network of Vegas sources with an analytical approach he honed working for Pro Football Focus. Hartstein tied for 52nd place (out of 1,598 entries) in the 2022 Westgate Las Vegas SuperContest, going 53-34-3 against the spread. His weekly Vegas contest selections form the basis of his NFL best bets column, which is 99-84-3 (+5.62 units) since its inception in 2022. Anyone who has followed him is WAY UP!

For the Divisional Round, Hartstein has locked in three confident best bets. If you successfully parlay his picks, you're looking at a payout of almost 6-1.

We can tell you Hartstein loves the Ravens (+1, 51.5) to cover on the road versus the Bills. "Baltimore ran for 271 yards in the first meeting. It won't be that easy Sunday in Buffalo against a healthier Bills' defense, but Lamar Jackson and Derrick Henry give the Ravens a substantial edge on the ground. Baltimore also gives up the fewest rushing yards per game... Look for the Ravens to win a high-scoring classic," Hartstein told SportsLine.

Hartstein also has locked in two other confident Divisional Round bets, including backing a SHOCKING team that has been "bad at making halftime adjustments" but Hartstein has it covering the first half spread! You ABSOLUTELY need to see his picks before betting on the NFL Divisional Round.
