USC Trojans

Last year, we looked at returning 3,000-yard passers, so the headline here shows how the Pac-12 has become more run-based, defensive minded of late.

And, of course, the conference's top two passers, Arizona's Matt Scott and USC's Matt Barkley, are both off to the NFL.

The returning members of the 2.5 K Club are:

• UCLA's Brett Hundley (3,740 yards, 29 TDs, 11 Ints, No. 4 in passing efficiency)
• Arizona State's Taylor Kelly (3,039 yards, 29 TDs, 9 Ints, No. 2 in passing efficiency)
• Washington's Keith Price (2,728 yards, 19 TDs, 13 Ints, No. 8 in passing efficiency)
• Oregon's Marcus Mariota (2,677 yards, 32 TDs, 6 Ints, No. 1 in passing efficiency)

There's a reason why Oregon, UCLA and Arizona State are highly thought of heading into 2013: Proven production returning behind center. And if Washington can get Price back to top form, the Huskies become a top-25 team.

So how does everyone else stack up? Which teams seem likely to get 2,500 yards passing next fall?

Well, there's lots of "To be determined" intrigue.

TBD, Arizona: B.J. Denker will enter fall camp atop the depth chart, but this one is far from over. If USC transfer Jesse Scroggins, who owns by far the biggest arms on the roster, wins the job, the Wildcats are almost sure to pass for 2,500 yards. Coach Rich Rodriguez, though widely viewed as a spread-option coach, showed last year he's comfortable throwing, so Denker or incoming freshman Anu Solomon also could put up solid passing numbers.

TBD, California: New coach Sonny Dykes likes to throw the rock around. Louisiana Tech averaged 351 yards passing per game last year. So whoever wins the QB job -- we're betting on Zach Kline -- will almost certainly hit the 2,500-yard mark.

TBD, Colorado: The Buffaloes struggled to the throw the ball last year, but new coach Mike MacIntyre might solve that, seeing his San Jose State Spartans passed for 332 yards a game last fall. Connor Wood, the frontrunner to win the job, has the arm to throw the ball around, but it's a matter of putting it all together.

TBD, Oregon State: Sean Mannion nearly made the above list, passing for 2,446 yards and 15 TDs with 13 interceptions last year, ranking fifth in the conference in passing efficiency and fourth in passing yards per game with 244.6. But he's still knotted with Cody Vaz in the competition for the starting job. If one guy starts the entire season, he will put up strong passing numbers because Mike Riley teams always do.

Kevin Hogan, Stanford: The Cardinal ranked 10th in the conference in passing last year with just 200 yards per game, but part of that was a scheme that played to a rugged defense and Hogan not winning the job until after midseason. Hogan is plenty capable, and his supporting cast is solid. Expect Hogan to at least hit the 2,500-yard mark.

TBD, USC: Whether it's Cody Kessler or Max Wittek, the USC QB will throw for at least 2,500 yards if he maintains his hold on the job. While Lane Kiffin likes balance, there are too many passing game weapons not to attack downfield, starting with All-American receiver Marqise Lee.

Travis Wilson, Utah: The Utes were last in the Pac-12 and 97th in the nation in passing in 2012, but Dennis Erickson is now their co-offensive coordinator. One of the original architects of the spread passing attack, it's highly likely Utah will substantially boost the 190.7 yards passing a game it produced last fall. Wilson is fully capable of throwing for 2,500 yards, and the Utes are solid at the receiver position.

Connor Halliday, Washington State: Halliday still isn't free-and-clear of redshirt freshman Austin Apodaca, but he's a solid frontrunner in the competition. Whoever wins the job, he will put up big numbers in Mike Leach's "Air Raid" system. The Cougars couldn't stick with a QB last year, going back and forth with Halliday and Jeff Tuel, but they still led the Pac-12 with 330.4 yards passing per game. If Halliday starts 12 games, he'll throw for 4,000 yards.

Here are some keys and storylines to watch this spring in the South Division. Yesterday Ted looked at the North Division.

ARIZONA WILDCATS

Start date: March 3

Spring game: April 13

What to watch:

1. New battery: The Wildcats are looking to replace a top-notch quarterback-center combo in Matt Scott and Kyle Quinn. The rock-solid duo helped produce one of the top offenses in the league. Jesse Scroggins and B.J. Denker are among those in the mix to run the offense and several returning offensive linemen are versatile enough to move around. Chris Putton and redshirt freshman Beau Boyster could be in the mix at center.
2. Many happy return(er)s: Arizona returns a big chunk of its offensive production -- including running back Ka'Deem Carey and receiver Austin Hill. Both should be on all sorts of preseason teams and awards watch lists. But behind the big names, there's also David Richards, Johnny Jackson, Tyler Slavin and Garic Wharton back in the mix.
3. No learning curve: Last spring, the talk was about Rich Rodriguez calling out his team for its lack of physical conditioning. The fact that the majority of the team understands what is expected -- and they don't need to spend the whole spring learning new systems, should be a huge help. Consider that the Wildcats return their entire defense from a group that was, at times, shaky, but will certainly benefit from another full season of playing in the 3-3-5 scheme.

ARIZONA STATE SUN DEVILS

Start date: March 19

Spring game: April 13

What to watch:

1. Plugging the middle: One of the few losses to ASU's roster is middle linebacker Brandon Magee -- a leader on and off the field and an all-around heck of a player. Carlos Mendoza looks to be a good fit -- though he's likely to miss spring while continuing to recover from a shoulder injury suffered against Illinois. Folks might remember his two interceptions before going down for the year.
2. Catching on: Unlike last spring, the Sun Devils have their quarterback. And he's a good one. Now, they need to find folks he can throw to. JC transfers De'Marieya Nelson (H-back, 6-3, 230) and Jaelen Strong (WR, 6-4, 205) are both big bodies who could step in and contribute immediately.
3. Wait and see: The kicker here is a lot of these players who are expected to compete won't arrive until the fall. So in the meantime, a lot of the younger players and redshirts will get a ton of reps in the system. And speaking of kicker, don't underestimate how much of an impact Josh Hubner made at punter. Iowan Matt Haack, who arrives in the fall, is a rugby-style kicker who can kick with either foot. That's just cool.

COLORADO BUFFALOES

Start date: March 7

Spring game: April 13

What to watch:

1. Meet your QB: Whomever it will be. There are five on the roster and a sixth coming in. Safe to say, quarterback play was extremely inconsistent last season for the Buffs. With an entirely new coaching staff coming in and installing the pistol, this could be one of the more interesting and wide-open position battles in the league.
2. Curious defense: One needs only to review Colorado's national rankings last year to realize they struggled. As one Buffs insider mentioned to me, they were ranked No. 1 in a lot of categories. Unfortunately, that "1" was followed by two more numbers. Only three defensive ends have playing experience. However a secondary that lacked experience in 2012 has a lot more looking into 2013.
3. Receiver options: The Buffs welcome back Paul Richardson, who missed all of last season with a knee injury. Colorado's premier offensive playmaker will be a nice veteran presence to whomever wins the quarterback job. Grayshirt Jeff Thomas also is back. An improved passing attack should help give the quarterback some confidence and open up the running game.

UCLA BRUINS

Start date: April 2

Spring game: April 27

What to watch:

1. Life after Franklin: The Bruins say goodbye to the best statistical back in school history -- leaving a huge void in the backfield. Johnathan Franklin was a great presence for young quarterback Brett Hundley, but now someone has to step up to fill that role, either solo or along with a committee. Look for Jordon James, Steven Manfro and Damien Thigpen to all get looks.
2. New No. 1: The Y-receiver, aka hybrid tight end, was filled wonderfully by Joseph Fauria -- Hundley's favorite red zone target. Darius Bell and Ian Taubler both had looks last year, but Fauria too will be tough to replace. Shaq Evans, Devin Fuller, Jordan Payton and Devin Lucien round out a pretty good receiving corps.
3. Secondary solutions: The Bruins must replace two corners and a safety -- Sheldon Price, Aaron Hester, Andrew Abbott -- and there isn't a ton of starting experience. Randall Goforth has five starts, but veterans such as Brandon Sermons and Anthony Jefferson have more special-teams experience than actual secondary play. Keep an eye on the secondary too when the Bruins start fall camp to see if any freshmen jump into the mix immediately.

USC TROJANS

Start date: TBD

Spring game: April 13

1. New defensive scheme: The Trojans will move to a 5-2 defensive scheme under Clancy Pendergast, and the spring drills will be the first opportunity to see the defense in action. The Trojans will have an experienced front seven, but four new starters are expected in the secondary.
2. Replacing Barkley: Max Wittek got the first extended audition in the battle to take over for Matt Barkley, but he didn’t do enough in two late-season starts to claim the job. Cody Kessler and freshman spring enrollee Max Browne also will be looking to take the reins at one of the glamour positions in college football.
3. Lane Kiffin on the hot seat: The Trojans are coming off a disappointing season, and the fans are howling in protest, but so far his boss Pat Haden has maintained full support for his coach. Now is the time for Kiffin to show why that support is warranted. -- Garry Paskwietz, WeAreSC

UTAH UTES

Start date: March 19

Spring game: April 20

What to watch:

1. Erickson impact: The biggest question was what sort of role Dennis Erickson would play in the offense once he arrived. We'll know sooner than later. He already has talked about putting an identity on the Utah offense. That starts in spring when routines are established and expectations are set. And with Erickson on board to give the offense a push, the expectations will be much higher.
2. Wilson maturing: That leads us to the presumptive starting quarterback -- Travis Wilson -- who jumped in midseason after Jordan Wynn got hurt and Jon Hays struggled to produce. Wilson went from OK to pretty good in just a few weeks. A nice jump considering his experience level. With an entire offseason knowing he'll be the starter -- and with Erickson and Brian Johnson molding him -- it will be interesting to see what progress he makes this spring.
3. D-line makeover: The Utes lose some talent on the defensive line -- specifically All-American defensive tackle Star Lotulelei. Look for DE/LB Trevor Reilly to spend more time with his hand down. Tenny Palepoi, LT Tuipulotu and JC transfer Sese Ianu could all see time in the mix at defensive tackle.
