Pac-12: Reggie Gilbert

You remember the three-headed monster, right? It's about returning production that will scare -- terrify! --opponents. Or not.

On offense, it's elite combinations at quarterback, running back and receiver.

On defense, it's elite combinations of a leading tackler, a leader in sacks and leader in interceptions.

This year, we're breaking things down by division. We've already done offense for the South and North divisions.

Next up: South Division defensive three-headed monsters.

1. USC

LB Hayes Pullard, DT Leonard Williams, S Su'a Cravens

The skinny: Pullard was second-team All-Pac-12 after leading the Trojans with 94 tackles. While DE Devon Kennard led the Trojans with nine sacks last year, Williams was a force inside with six. It's also possible, of course, that attention to Williams, a certain preseason All-American, will open things up for a DE/OLB, such as J.R. Tavai. Cravens is likely to become as a true sophomore an all-conference performer. He had four interceptions last year, second on the team.

2. UCLA

LB Eric Kendricks, OLB Kenny Orjioke, CB Ishmael Adams

The skinny: Kendricks ranked third in the Pac-12 with 8.8 tackles per game last year. Does he finally break through on the all-conference team after two years as an honorable mention? Orjioke is the frontrunner to replace Anthony Barr. He's 6-foot-4, 240 pounds and has tons of potential. He, however, had just 12 tackles and two sacks as a sophomore. Adams led the Bruins with four interceptions last year.

3. Arizona

LB Scooby Wright, DE Reggie Gilbert, "spur" LB Tra'Mayne Bondurant

The skinny: Wright earned honorable mention All-Pac-12 as a true freshman, finishing with 83 tackles, including 9.5 coming for a loss. With both MLB Jake Fischer and weakside LB Marquis Flowers gone, he seems like a favorite to lead the team in tackles, even if he stays at strongside backer. Gilbert ranked second on the team with four sacks, though it's possible the Wildcats defense will do some juggling to increase anemic sack numbers this fall. Or a new guy, such as LB Antonio Smothers or DL Jeff Worthy, will break through. Bondurant, a hybrid LB/safety, led the Wildcats with four interceptions in 2013.

4. Arizona State

LB Salamo Fiso, DE/OLB Viliami Latu, S Damarious Randall

The skinny: The Sun Devils are replacing nine starters on defense, but Randall and Fiso are two of the three returning starters. It is notable that coach Todd Graham has been moving guys around on defense this spring, so ultimate positions are a matter of conjecture at this point. Fiso ranked fourth on the team with 71 tackles. Sophomore Latu might have a lead in the battle to replace Carl Bradford at the highly productive "devil" LB position. Randall had three interceptions last year.

5. Utah

LB Gionni Paul, OLB Jacoby Hale, S Eric Rowe

The skinny: Paul, a Miami transfer, is drawing raves this spring. He was a terror on the scout team a year ago. Hale is likely to replace Trevor Reilly, who led the Utes in tackles and sacks last year, at the "stud" linebacker. He was second on the Utes with 10 tackles for a loss and 6.5 sacks a year ago. As for the Utes’ leader for interceptions, well, funny you should ask about a team that had just three picks all of last year, tied for fewest in the nation. We're going with Rowe, even though he didn't have a pick in 2013 and had just one in 2012.

6. Colorado

LB Addison Gillam, TBA, CB Greg Henderson

The skinny: Along with Wright and UCLA's Myles Jack, Gillam was a true freshman LB revelation last year. He led the Buffaloes with 107 tackles. He might be a good bet to lead the team in sacks, too. The Buffs are replacing leading sacker Chidera Uzo-Diribe (4), and it's unclear who will fill that void. D-lineman Samson Kafovalu is a possibility, but he's sitting out spring focusing on academics. Derek McCartney -- yeah, that McCartney -- has been playing well this spring. Henderson led the Buffaloes with four picks a year ago.

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.
