NFL preseason same game parlay: We’re backing a side and a total based on preseason rotations, limited starter reps, and historically low early scoring.
If you’ve been chomping at the bit to get some NFL action on the books, tonight is finally your chance.
Week 1 of the NFL preseason kicks off with a West Coast matchup as the Las Vegas Raiders visit the Seattle Seahawks on Thursday, August 7. While the game won’t feature many household names for long, it presents a clear value opportunity for bettors constructing a same game parlay. We’re pairing Seahawks +4.5 against the spread and the Under 37.5 total points, a duo rooted in historical preseason trends, expected snap counts, and Seattle’s depth advantage.
Preseason games rarely follow regular-season logic. Instead, they reward bettors who evaluate coaching tendencies, quarterback rotations, and situational depth. This parlay reflects that logic, offering +190 odds on a script that leans toward defensive control and backup-heavy football.
NFL Preseason Same Game Parlay: Raiders vs. Seahawks
Leg 1: Seahawks +4.5
The Raiders opened as slight underdogs but steamed to –4.5 favorites as speculation swirled that starters could see more action. However, reports indicate Las Vegas will only give a brief run to starters, if at all. Conversely, Mike Macdonald has already stated Seattle’s key veterans, like Sam Darnold, will likely sit, meaning we’ll see backups from the jump.

That’s not a bad thing. Seattle’s quarterback depth (including Jalen Milroe) and defensive roster projects stronger than Las Vegas’s second-stringers. In the preseason, depth wins. Getting more than a field goal with the deeper roster makes Seattle a sharp ATS leg.
Leg 2: Under 37.5 Total Points
Since 2018, preseason unders have hit at over a 55% clip. Week 1 games often feature conservative game plans, longer drives with limited play clocks and a higher volume of field goals. In this matchup, neither team is expected to aggressively push the pace. The Raiders’ backup offense is limited, and Seattle won’t deploy much of its starting weaponry.
Pairing the Under with a Seattle cover aligns with a realistic game script: sluggish drives, red zone field goals, and a fourth quarter filled with third-stringers.
| Leg | Pick | Odds | Rationale |
|---|---|---|---|
| 1 | Seahawks +4.5 (ATS) | –110 | Seattle’s depth, especially at QB and defense, provides value in a backup-heavy game script. |
| 2 | Under 37.5 Total Points | –110 | Preseason unders historically hit. Conservative play-calling and limited starters suggest a low-scoring pace. |
| Total Parlay Odds | +190 | ||
Mike Macdonald loves the intent with which DeMarcus Lawrence practices, even in Year 12.
