Jordan Holmes

Bio: Holmes went to Oregon from Yuba City, Calif., where he was named All-Area player of the year in 2005.

Key achievements: Holmes redshirted as a freshman, provided depth as a redshirt freshman and then saw four starts in his redshirt sophomore year. In 2009, Holmes started 13 games at center and became a team captain. He received honorable mention All-Pac-10 that season.

In 2010, Holmes anchored an offensive line that created a devasting rushing attack fueled by running back LaMichael James. The offense helped the Ducks go 12-0 during the regular season and advance to the BCS National Championship Game.

Hamani Stevens

Bio: The Ducks recruited Stevens out of Hemet High School in California. He redshirted in 2008 before starting a religious mission. He returned to Oregon in 2011 to become a mainstay in a dominant offensive line.

Key achievements: Stevens started every game over his final two seasons. He appeared in 13 in 2013 and then 15 in 2014. That season, the Ducks won the Pac-12 championship and defeated Florida State in the Rose Bowl/college football playoff game.

Oregon ranked third in the country in total offense (547 yards per game) and fourth in scoring offense (45.4 points per game) in 2014.

Stevens played a prominent role along a line that helped quarterback Marcus Mariota claim the 2014 Heisman trophy.

Stevens is one of the program’s five players to record more than 1,000 snaps, and the only one on offense (1,056).
