NFL Preseason Week 2 is here, and tonight's two-game slate gives us plenty to dig into as teams continue rounding into form. The Houston Texans plan to unleash a much fuller complement of starters after nearly sitting everyone in Week 1, while San Francisco and Los Angeles enter with matching plans to get their top players a series of snaps before handing things off to the backups. That mix of committed, ahead-of-time plans makes tonight one of the clearer nights of the preseason to build some real NFL best bets today.

🔥 NFL Preseason Week 2 Picks, Predictions & Best Bets Today, 8/20 

Preseason Week 2 brings a lighter two-game slate tonight, but both matchups carry real intrigue after teams spent the opener figuring out their approach. Houston nearly sat every starter in its debut and now plans a much fuller look at its top players, while San Francisco and Los Angeles enter with matching plans to get their starters some run before handing things off. That shift toward more meaningful participation compared to Week 1 makes tonight a genuinely useful night for NFL best bets today.

With just two games on the board, there is less ground to cover but more clarity to work with on both. Some coaches have been unusually direct about exactly how much their starters will play, a welcome change from the guesswork that often defines these early preseason weeks. That kind of transparency gives sharp bettors a real foundation to build from, and it is exactly what makes tonight's slate stand out among NFL best bets today. Between two committed coaching staffs and rising stakes for roster battles, this is shaping up as a strong night of NFL predictions.

 

 

 

👀 Best Matchups & Players To Watch Today

Houston's turnaround in approach is the headline story of the night. After keeping nearly every starter out of Week 1, DeMeco Ryans confirmed a much fuller group will suit up against Las Vegas, including C.J. Stroud, Will Anderson, and Danielle Hunter all getting their first live snaps of the preseason. Fernando Mendoza also gets another look after a promising debut last week, going 10-for-16 for 97 yards and a TD. That shift toward real starter usage on one side of this matchup gives it more weight than a typical Week 2 game, making it a clear focal point among our NFL best bets today.

The nightcap between San Francisco and Los Angeles offers the cleanest, most symmetrical plan of the night. Chargers head coach Jim Harbaugh confirmed starters on both sides will play a full series before handing things off to backups for the rest of the game, a plan coordinated directly with Kyle Shanahan. Brock Purdy has a good chance to see his first live action of the preseason as part of that plan, a notable step up after sitting out Week 1 entirely. With both coaching staffs aligned on exactly how the night will unfold, this matchup stands out as one of the clearer reads among tonight's NFL best bets today.

🏉 49ers vs. Chargers Prediction, Thursday, August 20th: Under 38.5 Points (Sign Up at EDGE Boost)

We’re going to focus on the California clash of 49ers vs. Chargers. Both teams are committing real starters to this game, but that does not automatically point to more scoring, especially when both rosters bring legitimate strength on defense as well as offense. Only five of 16 games across the entire Week 1 slate finished above 38 points, a clear sign that early preseason offenses, even with starters involved, still take time to find rhythm. That trend, paired with two capable defensive units on the field tonight, is why this is the focus of our NFL best bets today.

San Fran and LA both plan to play their starting QBs for a limited stretch before turning things over to backups, which caps the offensive ceiling on both sides regardless of who is on the field early. Once the backups take over, disjointed execution and conservative play-calling tend to take hold, a pattern that showed up across most of last week's slate. With both starting units getting only a taste of run before less experienced personnel finish the game, this profiles as another lower-scoring night, reinforcing our NFL best bets today.

Just as important, defense figures to play a real role here beyond the box score. Both teams feature units capable of disrupting rhythm early, and a limited sample of starter snaps means neither offense gets much time to establish real flow before adjustments are needed. Between the modest track record for scoring so far this preseason and two defenses capable of setting the tone in their brief window with the starters, the path to a lower-scoring finish looks clear, hence the main target of our NFL best bets today.

Lock in 49ers vs. Chargers under 38.5 points after signing up at EDGE Boost.
