Arch Manning holds the lead in the 2027 NFL Draft first-overall market as the Texas quarterback enters his junior season with the Longhorns, backed by strong arm talent, athleticism, and the Manning family pedigree that keeps him atop most preseason big boards. Darian Mensah has climbed sharply after transferring to Miami and delivering dominant early outputs, including 401 passing yards and five touchdowns against Stanford plus near-perfect efficiency in a blowout over Florida A&M, elevating his Heisman and draft visibility. CJ Carr continues steady production at Notre Dame while Dante Moore and others like LaNorris Sellers and Julian Sayin await larger sample sizes from the 2026 campaign. Traders price these probabilities based on preseason scouting combined with the first two weeks of college football results, with further movement expected as conference play intensifies and roster health factors emerge.
