Games such as Bills vs. Patriots (+2.5), Eagles vs. Giants (+3) and Texans vs. Titans (-1.5) all have a couple of things in common when deciding which contests to include in a Week 18 NFL parlay. They all involve one team that's locked into its current playoff seed, and all three of those teams are facing an opponent that has already been eliminated from postseason contention. The slim NFL spreads for these games indicate that not even sportsbooks know what to expect. Could you possibly use that to your advantage with your Week 18 NFL best bets?

Which NFL trends and NFL betting lines could help with your NFL betting strategy? Before you make any Week 18 NFL picks or NFL 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 ATS. His weekly Vegas contest selections form the basis of his NFL best bets column, which is 99-78-3 (+12.18 units) since its inception in 2022. Anyone who has followed him is WAY UP!

For Week 18, 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 Raiders (+5, 41) to cover at home versus the Chargers. "I like the Raiders to be competitive. Their offensive line is playing its best ball of the season, Aidan O'Connell has looked competent, and Brock Bowers and Jakobi Meyers are legitimate weapons. Vegas' defense has given up 4.9 yards per play over the past three games. The Raiders finished 3-1 under Antonio Pierce last season -- the loss coming by a field goal -- and enter this game on a two-game win streak," Hartstein told SportsLine.

Hartstein also has locked in two other confident Week 18 bets, including backing a SHOCKING team that is "averaging 7.0 yards per play" over its last three games to cover! You ABSOLUTELY need to see his picks before betting on NFL Week 18.
