Oregon Ducks: Todd Barr

Our look at position groups in the Pac-12 continues.

Arizona: Coach Rich Rodriguez is confident in both Reggie Gilbert and Dan Pettinato and anxious to get junior-college transfers Jeff Worthy, who also spent a year at Boise State, and Jerod Cody acclimated to the system. Calvin Allen, Jack Banda and Luca Bruno are coming off redshirt seasons and represent a group Rodriguez said the team needs production from.

Arizona State: With the departure of Gannon Conway and Davon Coleman, there is a question about the team's depth at end. Without Will Sutton clogging things up next year, the Sun Devils' lack of experience is even more of a concern. Sean O'Grady backed up Conway and Coleman last year, but ASU has several well-regarded junior-college transfers in Edmond Boateng, Marcus Hardison and Demetrius Cherry.

California: The Bears list seven defensive ends, but former junior-college transfer Kyle Kragen and Puka Lopa gained the most experience last season listed at the rush position. Antione Davis was outgoing starter Dan Camporeale's primary backup, but Brennan Scarlett's return is more important. He started nine games in 2012 and has been cleared to play following a hand issue that cost him the 2013 season. Todd Barr, Sione Sina and recent-transfer Jonathan Johnson are also in the mix.

Colorado: Colorado must replace Chidera Uzo-Diribe, but Juda Parker is back for his senior season, and several others have game experience. Samson Kafovalu is the likely candidate to start opposite him after making 18 tackles in seven games last year. Jimmie Gilbert was Uzo-Diribe's backup, Kirk Poston and De'Jon Wilson also played.

Oregon: The Ducks took a hit with the departure of Taylor Hart, who was named second-team All-Pac-12, but have a talented player in Arik Armstead lined up to take his spot. Armstead started five times in 2013 and left the basketball team midseason to shift his focus back to football. T.J. Daniel, Jason Sloan are projected to be in the mix for playing time.

Oregon State: Scott Crichton is gone, but Dylan Wynn remains and will likely be the Beavers' best defensive player a year after finishing fourth on the team in tackles. Lavonte Barnett, Crichton's primary backup in 2013, and Jaswha James figure to compete for the starting job, but there are two others to keep an eye on. Obum Gwacham recently switched from receiver and Mike Riley has been complimentary of Titus Failauga, who is coming off his redshirt.

Stanford: Henry Anderson has a chance to be one of the best defensive players in the conference and Blake Lueders, who switched from OLB, began the spring atop the depth chart. The intriguing prospect is Luke Kaumatule, who was recruited to play defense but began 2013 as the team's starting tight end. Spring will be important for his development, but his raw ability is impressive.

UCLA: Both Ellis McCarthy and Eddie Vanderdoes were all-Pac-12 honorable mention last season and highlight a talented UCLA defensive line. Their return will help account for the loss of Cassius Marsh, who started 12 games last year. Both McCarthy and Vanderdoes can play inside or outside, but the Bruins listed them both at end. Highly recruited DE Kylie Fitts saw playing time as a true freshman last season.

USC: Leonard Williams, the only sophomore named first-team all-Pac-12 on defense last season, is the best in the conference. Delvon Simmons, who sat out last season after transferring from Texas Tech, has a lot of game experience. He started 12 games for the Red Raiders in 2012 and had regular playing time as a freshman there in 2011. Both Simmons and J.R. Tavai, who was an all-Pac-12 honorable mention selection, can play inside or outside.

Utah: There's no replacing Trevor Reilly, who made 100 tackles despite lingering effects from a torn ACL, but Nate Orchard and Hunter Dimick both saw extensive playing time last season. The Utes have five other defensive ends on the roster, but of that group only LT Filiaga made a tackle last season.

Washington: The Huskies are in great shape with the return of Hau'oli Kikaha, a second-team All-Pac-12 selection, Cory Littleton and Evan Hudson. Josh Shirley has 10 career starts, while Joe Mathis and Psalm Wooching provide depth.

Washington State: With Toni Pole expected to move back inside, the depth chart will look similar to how it did going into last season, minus Matt Bock. After making 50 tackles last year, Xavier Cooper will start on one side, with Destiny Vaeao and Lyman Faoliu strong candidates for more playing time. Emmitt Su'a-Kalio is coming off a redshirt, and the Cougars also signed a pair of defensive ends from Hawaii in Kingston Fernandez and Hercules Mata'afa.

After the Ducks program began to take off in the mid-1990s, California hired former Ducks' offensive coordinator Jeff Tedford in 2002. As the Ducks' upward climb reached a standstill, Cal stepped up and looked like it might be the next in line to challenge USC.

The Golden Bears did win four of five games with the Ducks between 2004 and 2008, including a game for the ages in 2007. After they walked out of Autzen Stadium with a 31-24 win over the No. 5 Ducks, things began to change between the two schools. Cal did win the following season in Berkeley, as the Ducks fumbled gave away a game they dominated. Starting in the class of 2008, the Bears responded by going on an unprecedented run of recruiting success. The Ducks began to dominate the series on the field with a 42-3 win over the Bears in 2009. Despite the dominant performance over the then-No. 6 Bears, Cal beat the Ducks head-to-head for a number of elite recruits from 2008 to 2012.

Whether it was location, academics, Cal's plans for facilities upgrades -- which are now complete -- or former Cal assistant -- and current Washington assistant -- Tosh Lupoi, the Bears won the majority of the recruiting battles between the two schools. Similar to the recent history with USC, the Ducks don't care about recruiting rankings as much as they do the on-field results.
