All three have been named to the preseason watch list for the Outland Trophy, which is awarded every season to the best interior lineman in college football.
Powers, a senior, and Evans, a redshirt junior, have started a combined 46 games over the past two seasons, and Samia, a senior, has started 34 games over the past three seasons.
Samia is the most experienced of the three returning Sooner linemen, but offensive line coach Bill Bedenbaugh calls Powers the most consistent performer.
The three Sooner offensive linemen, holdovers from one of college football’s best offensive lines in 2017, are among 82 candidates on the preseason watch list for the 2018 Outland Trophy.
