Herbert averaged 227.6 yards passing and 18 yards rushing per game in 2024.

Josh Allen, last year's NFL MVP, enters his eighth season after being drafted in the first round of the 2018 NFL Draft by the Bills. Allen and Buffalo will be facing a Ravens team they eliminated in the divisional round of last year's playoffs. Allen has several prop lines available, including passing yards (236.5), rushing yards (34.5) and passing touchdowns (1.5). Allen threw for 3,731 yards and 28 touchdowns last season, the first time he did not surpass 4,000 yards since 2019.

Lamar Jackson, who put up MVP-type numbers with 4,172 yards passing with 41 touchdowns and just four interceptions, will face Allen and the Bills in the opener. Among Jackson's many prop lines include passing + rushing yards (280.5), longest completion (35.5) and interceptions (0.5).
