Week 1 NFL Player Props Preview: Star Quarterbacks in Focus
Underdog Fantasy offers a unique “higher” or “lower” format for player props, making it easy to predict how your favorite stars will perform. Here’s a look at some key Week 1 matchups and prop lines:
Justin Herbert (Chargers) vs. Chiefs (in Brazil)
Justin Herbert aims to lead the Chargers back to the postseason. His Week 1 prop lines include:
- Passing Yards: 233.5
- Passing Touchdowns: 1.5
- Rushing Yards: 14.5
Last season, Herbert averaged 227.6 passing yards and 18 rushing yards per game, making these lines intriguing for his opening performance against a tough Chiefs defense.

Josh Allen (Bills) vs. Ravens
Josh Allen, last year’s NFL MVP, enters his eighth season with the Bills. He’ll face a Ravens team they eliminated in last year’s divisional round. His prop lines include:
- Passing Yards: 236.5
- Rushing Yards: 34.5
- Passing Touchdowns: 1.5
Allen threw for 3,731 yards and 28 touchdowns last season, marking the first time since 2019 he didn’t surpass 4,000 passing yards. Can he start strong against a formidable Baltimore defense?
Lamar Jackson (Ravens) vs. Bills
Lamar Jackson, coming off an MVP-caliber season with 4,172 passing yards, 41 touchdowns, and just four interceptions, will go head-to-head with Josh Allen. Key prop lines for Jackson include:
- Passing + Rushing Yards: 280.5
- Longest Completion: 35.5
- Interceptions: 0.5
In their last playoff encounter, Jackson completed 18 of 25 passes for 254 yards and two touchdowns, plus 39 rushing yards. His dual-threat ability makes his prop lines particularly exciting.
