Producing successive Heisman Trophy-winning quarterbacks and likely consecutive number one NFL draft picks is no easy feat, but it helps if you have one of the best offensive lines around. In 2017, Baker Mayfield played behind an Oklahoma Sooners O-Line that featured Orlando Brown – a third-round selection by the Baltimore Ravens in 2018 – Dru Samia, Ben Powers and Bobby Evans en route to winning the Heisman and becoming the top pick for the Cleveland Browns in the 2018 NFL Draft. Samia, Powers and Evans all returned last year when the Sooners allowed just 19 sacks, providing the foundation for Kyler Murray to win college football's highest individual honour and become the favourite for the first overall pick.
