Week 1 NFL props preview

A pair of former No. 1 overall picks will square off in Panthers vs. Jaguars as Bryce Young and Trevor Lawrence share a field. They have both the same passing touchdowns NFL prop of 1.5, as well as the same rushing yards bar of 13.5 yards. However, Lawrence's passing yardage prop of 235.5 yards is slightly above Young's mark of 215.5 yards, though the latter could have the easier matchup. The Jags finished last in passing defense in 2024 as 13 of the 17 starting quarterbacks they faced went over 215.5 passing yards.

Daniel Jones is the new QB1 in Indianapolis, but the Colts' offensive philosophy should remain the same with Jones having the same dual-threat abilities as Anthony Richardson. Colts vs. Dolphins at 1 p.m. ET has Jones' rushing yards over/under at 30.5 yards, per Underdog Fantasy, as the former Giant averaged 33.1 yards on the ground over his last 17 starts. Miami, however, could provide a challenge to Jones picking up yards with his legs as the 10.4 rushing yards per game it allowed to opposing quarterbacks last year were the second-fewest in the NFL.

James Cook finally got the contract extension he was hoping for and will get a chance to prove his value versus the NFL's reigning top run defense. Bills vs. Ravens on Sunday night will see the teams squaring off for the third time in less than a calendar year. Cook averaged 65 scrimmage yards across those two meetings as Buffalo will rely on him to help out in the passing game with Baltimore so stout versus the run. Cook has a rushing + receiving yards O/U of 66.5 yards at Underdog Fantasy, while his rushing yards prop, alone, stands at 52.5 yards. Bet at Underdog Fantasy and get $50 in bonus bets after making a $5 bet:
