Buchner wouldn’t start for Oklahoma for his first 2 years

Kyler Murray and his Heisman season: While Murray was a top recruit out of Allen (Texas) High School — where he went 43-0 as a starter and won three state championships — he struggled in a muddled quarterback situation at Texas A&M and then sat out a year after transferring to OU. He spent last season as the Mayfield’s backup, only throwing 21 passes. He wasn’t officially named Oklahoma’s starter until Aug. 22.

Baker Mayfield played a year for Texas Tech and then sat out a year before starting for Oklahoma so he was in his third year of college when he became their starter.
