Jones, of course, is the grandson of Dallas Cowboys owner Jerry Jones. He currently holds no FBS offers according to his 247 Sports profile.
Oklahoma is presumably bringing Jones in as a potential walk-on candidate. The Sooners already have quarterbacks committed in the 2018 (Tanner Mordecai) and 2019 (Spencer Rattler) classes.
The Sooners have a rich history of playing walk-ons. Current quarterback Baker Mayfield started his career at Texas Tech, and later at Oklahoma, as a walk-on. Several other players on the roster, including Erick Wren, Jaxon Uhles and Nick Basquine, have earned scholarships and significant playing time as walk-ons.
