The Texas and Oklahoma high schools that supply much of the Big 12’s talent also overwhelmingly use up-tempo spread schemes. Big 12 coaches have adjusted by running schemes their players can master quickly. That helps in the short term, but it has become a key recruiting point for coaches from other leagues when they enter Big 12 territory. The median Big 12 draft position for offensive linemen is 164. That’s 46.5 spots below the Pac-12, 53 spots below the ACC, 62 spots below the SEC and 78 spots below the Big Ten. Given those numbers, is it any wonder the top-ranked offensive tackle recruit in Texas in 2017 (Walker Little of Bellaire) signed with Stanford and the next-highest-ranked tackle (Austin Deculus of Cypress) signed with LSU?
