Oklahoma football: A look back at the 2015 recruiting class

No. 12 – A.D. Miller | wide receiver| Original rank: 21

A.D. Miller had all the measurables to become a star, especially in the Lincoln Riley offense, but found himself stuck behind a ton of talented players on the depth chart during his career at Oklahoma. Despite that, he still managed to catch 21 passes for 236 yards and four touchdowns during his three seasons at Oklahoma. He will spend his redshirt senior year at Illinois after announcing his intentions to grad transfer this past winter. Grade: Contributor

No. 11 – Marquise Overton | defensive end | Original rank: No. 12

A high-upside defensive lineman, Overton has flashed his ablities at different times, starting nine games his redshirt sophomore year before settling into more  of a roleplayer spot in his junior season.

No. 10 – Kahlil Haughton | defensive back | Original rank: No. 6
