CBS Sports' Brandon Marcello has made a bold prediction for the Oklahoma Sooners' 2026 season, stating that quarterback John Mateer will be a strong contender for the Heisman Trophy. After a much-improved offensive performance in 2025, the Sooners are looking to build on that momentum. Mateer, who is entering his second season under offensive coordinator Ben Arbuckle, is focusing on refining his throwing mechanics and footwork this offseason. With critical early-season matchups against Michigan, Georgia, and Texas, success in these games could solidify his status as a Heisman candidate. If Mateer performs well, it would indicate significant progress for the Sooners' offense, potentially leading to another playoff appearance. The combination of a healthy Mateer and a strong defense under head coach Brent Venables could set the stage for a successful season ahead.
