When the season kicked off, the Week 13 matchups of Eagles vs. Ravens and 49ers vs. Bills looked like a pair of potential Super Bowl previews. While three of the four teams have played like contenders, an injury-decimated Niners team has not. San Fran is a 7-point underdog, per the Week 13 NFL odds, as it will visit Buffalo on Sunday night. Meanwhile, Ravens vs. Eagles (+3) could very well be a matchup we see again in February. These two contests highlight Sunday's Week 13 NFL schedule and are two interesting contests to include in a Week 13 NFL parlay.

Which NFL trends and NFL betting lines could help with your NFL betting strategy? Before you make any Week 13 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 93-69-3 (57.4%, +16.34 units) since its inception in 2022. Anyone who has followed him is WAY UP!

For Week 13, 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 Steelers (+3, 47.5) to cover on the road versus the Bengals. "The Steelers are back in their preferred role as underdogs, where they thrive. They're 4-0 ATS as dogs this season, winning all four outright, and should cover here despite Cincinnati's desperation. The Bengals have given up 5.8 yards per play over their last three games. Each of the Steelers' three losses has been tight, as they lost by a field goal twice and then 24-19 in a Cleveland snowstorm," Hartstein told SportsLine.

Hartstein also has locked in two other confident Week 13 bets, including backing a SHOCKING team he says will make the opposing quarterback "uncomfortable with its NFL-best pressure rate!" You ABSOLUTELY need to see his picks before betting on NFL Week 13.
