Stanford Football: Tyrequek Zimmerman

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. Wednesday we looked at defenses in the South.

Next up: North Division defensive three-headed monsters.

1. Stanford

LB A.J. Tarpley, DE Henry Anderson, S Jordan Richards

The skinny: The Cardinal lose their top tackler (Shayne Skov) and top sack guy (Trent Murphy). But there are others ready to take control. Tarpley has long been one of the league’s most underappreciated linebackers (93 tackles last season) and Anderson’s return boosts a front seven that should continue to party in the backfield. Richards is solid at one safety spot, though there are some questions about who will play opposite him. The Cardinal still boast the top defense in the league until proven otherwise.

2. Washington

LB Shaq Thompson, DE Hau’oli Kikaha, DB Marcus Peters

The skinny: The Huskies have some losses, like everyone else in the country, but there is plenty of talent coming back for the new coaching staff to work with. That returning production is enough to slot them No. 2. Thompson continues to get better with each season and appears on the verge of a breakout year. Kikaha has not-so-quietly turned into one of the Pac-12’s most feared rushers (13 sacks last season) and Peters is back after making five interceptions last season. They lose some leadership with the departure of Sean Parker and there's some question marks in the secondary. But this should be a salty group in 2014.

3. Oregon

LB Derrick Malone, DE/OLB Tony Washington, CB Ifo Ekpre-Olomu.

The skinny: Despite losing Avery Patterson, Brian Jackson and Terrance Mitchell, the secondary still boasts one of the top defensive backs in the country in Ekpre-Olomu. Mitchell led the team with five picks in 2013, but a lot of teams opted not to test Ekpre-Olomu. Malone is back after making 105 tackles, and Rodney Hardrick should be on his heels as top tackler. The linebackers should be a strength. Washington returns after recording 7.5 sacks to go with 12 tackles for a loss. Now, if they could just get off the dang field on third down ...

4. Oregon State

S Tyrequek Zimmerman, DE Dylan Wynn, CB Steven Nelson

The skinny: Zimmerman brings his 104 tackles back from last season and the return of OLB Michael Doctor, the team’s leading tackler in 2012, should be a nice boost. Replacing the production of Scott Crichton and his 7.5 sacks will be difficult. Linebacker D.J. Alexander and Wynn should see their share of time in the backfield. Nelson, a former junior college transfer, had a spectacular first season with the Beavers with a team-high six interceptions (tied with Rashaad Reynolds) and eight breakups.

5. Washington State

LB Darryl Monroe, DT Xavier Cooper, ?

The skinny: Do-all safety Deone Bucannon is gone after leading the team in tackles (114) and interceptions (6). He was an All-American for a reason. Monroe is an obvious choice for tackles, and Cooper is the obvious choice for sacks. But the secondary is wide open. Mike Leach has essentially said all four spots in the secondary are up for grabs. Clouding the issues is the future of cornerback Daquawn Brown, who has legitimate experience but also some legal hurdles to overcome.

6. California

S Michael Lowe, LB Jalen Jefferson, S Avery Sebastian?

The skinny: We all know about the defensive injury issues the Bears had last season, which is why Lowe returns as the leading tackler and tied for the lead in interceptions with one (the Bears only had five all last season). Jefferson returns with the most sacks, and Kyle Kragen appears to be a good fit for the scheme. (Remember when Kameron Jackson had three in one game!) We’ll see how oft-injured but talented Stefan McClure fares at safety. Getting Sebastian back from injury will help in the secondary. The pass rush should be improved with Brennan Scarlett’s return.
Our look at position groups in the Pac-12 continues with the safeties.

Arizona: The Wildcats have a lot of experience at safety with a combined 78 starts between Jourdon Grandon, Tra'Mayne Bondurant and Jared Tevis. All three of their backups on the AdvoCare V100 Bowl depth chart -- Anthony Lopez, William Parks and Jamar Allah -- also return.

Arizona State: Damarious Randall returns as one of the more talented safeties in the conference after a season in which he finished tied for third on the team with 71 tackles. Marcus Ball is a strong candidate to eventually earn the job next to Randall, but he's still working his way back from a clavicle injury that cost him the 2013 season. Laiu Moeakiola, who appeared in 10 games last year as a reserve, James Johnson, Jayme Otomewo and Ezekiel Bishop are other names to watch.

California: Cal started five different players at safety last year and four of them -- Michael Lowe, Cameron Walker, Avery Sebastian and Damariay Drew -- will be back. Sebastian began the year in the starting lineup and had an interception and 10 tackles before suffering a season-ending Achilles tear in the first half of the season opener. Look for him to regain his starting job next to Lowe.

Colorado: The Buffs need to replace SS Parker Orms, who had 26 career starts and 10 last season, but FS Jered Bell will return. All three of the players competing to replace Orms -- Marques Mosley, Terrel Smith and Tedric Thompson -- have started at least three games. Smith redshirted last season after he underwent shoulder surgery and has 19 career starts.

Oregon: The Ducks lose both Brian Jackson and Avery Patterson from a secondary that has consistently been among the nation's best. Fifth-year senior Erick Dargan, Patterson's high school teammate, looks to slide into his first full-time starting role after three years of meaningful contributions on both special teams and reserve duty. Opposite him, Issac Dixon is the presumed favorite with Tyree Robinson and Reggie Daniels also in the mix.

Oregon State: The Beavers have both Ryan Murphy and Tyrequek Zimmerman back for their third year as starters, which should help soften the blow of losing CB Rashaad Reynolds. A few others to watch are sophomore Cyril Noland-Lewis, Justin Strong, Brandon Arnold, Zack Robinson and walk-on Micah Audiss, who was No. 2 behind Zimmerman in the season-ending depth chart.

Stanford: Ed Reynolds' early departure for the NFL creates the one real unknown spot for the Cardinal. Two former offensive players -- QB Dallas Lloyd and WR Kodi Whitfield -- are in the competition for the vacant spot, as is Kyle Olugbode. Zach Hoffpauir will join the competition once baseball season is over. The winner will play next to Jordan Richards, a senior who has started the past two seasons and played regularly as a freshman.

UCLA: Starters Randall Goforth and Anthony Jefferson are both back after being named all-Pac-12 honorable mention last season. Two names to watch are Tahaan Goodman and Tyler Foreman, both of whom arrived as part of the Class of 2013.

USC: Su'a Cravens and Josh Shaw are back, but the Trojans will have to replace Dion Bailey, who left early for the NFL after converting to safety from linebacker last year. Shaw could wind up back at corner, which would open the door for Leon McQuay III. Gerald Bowman got a medical redshirt after appearing in three games last year and should provide depth.

Utah: Veteran Eric Rowe is set to begin his fourth year as a starter in the Utes' secondary, but he'll play next to a new player with Michael Walker out of eligibility. Charles Henderson was Walker's primary backup last season, but look for junior-college transfer Tevin Carter -- a former Cal Bear -- to challenge him for the starting job.

Washington: The Huskies are looking to fill both starting spots and will likely do so with young players. Sophomores Brandon Beaver, Kevin King and Trevor Walker all saw spot duty last year and the program signed an impressive crop of high school safeties, including Bellevue's Bishard “Budda” Baker.

Washington State: Replacing Deone Bucannon means replacing one of the school's all-time greats at his position. Isaac Dotson looks like the favorite to take that spot, but will be pushed by David Bucannon, Darius Lemora and true freshman Markell Sanders, who arrived for spring practice.
