Arch Manning won’t step on the field for the University of Texas until 2023 but he’s already the favorite to be the No. 1 overall pick in the NFL Draft four years from now.SportsBetting.ag has opened a trio of prop bets around Manning since the consensus No. 1 prospect in the Class of 2023 committed to the Longhorns last week.The potential action begins with the five-star prospect being offered at +450 to forgo a redshirt season and -190 to start immediately as a true freshman.Manning chose Texas over a host of powerhouse programs including Alabama, Georgia, LSU and Clemson. The expectation is that the 6-foot-4 New Orleans native will be given an immediate opportunity to take the reins of the Longhorns’ offense.Manning is the nephew of former NFL greats Peyton and Eli Manning and the grandson of Archie Manning. He is the son of Cooper Manning.Arch Manning threw for 26 touchdowns and ran for seven more as a junior at Isidore Newman High School. He could be the starting quarterback for Texas in 2025, which would be his junior season and the year the Longhorns enter the SEC.Manning’s commitment led to a recruiting surge for Longhorns coach Steve Sarkisian.Seven players have committed to the program since Manning’s announcement, including five on Sunday alone. Five-star defensive back Derek Williams added his commitment on Monday.
