A glimpse at what's going on in the Pac-12 North:
CALIFORNIA
Spring start: March 31
Spring game: April 26
What to watch:
Kaufman effect: New defensive coordinator Art Kaufman has his work cut out for him after inheriting a Cal defense that allowed 45.9 points per game during coach Sonny Dykes' first season. This isn't a case of needing few tweaks back to respectability; it could take a complete overhaul to get things turned in the right direction.
Developing Goff:Jared Goff jumped right into the starting job as a true freshman, and his considerable talent was evident from the beginning. With a year under his belt, Goff will take on more of a leadership role as he begins his first spring as the unquestioned starter.
Get healthy: Cal's 2013 season was met with a rash of injuries that made one of the nation's toughest schedules even tougher to navigate. The Golden Bears will show extreme caution during the spring as to remain as healthy as possible for fall camp.
OREGON
Spring start: April 1
Spring game: May 3
What to watch:
Life after Mariota? Much like Andrew Luck's 2011 season at Stanford, it's clear Marcus Mariota is headed into his final season as the Ducks quarterback despite having two years of eligibility left. It really began last season, but Jeff Lockie and Jake Rodrigues, who served as dual backups last year, will continue to compete for the soon-to-be-vacated starting job.
Pellum takes over: Don Pellum replaces longtime defensive coordinator Nick Aliotti, who held the job for the previous 17 seasons. It'll take some adjusting without Aliotti around, but Pellum, who has spent 23 years coaching at Oregon, figures to make it close to a seamless transition.
Building receiver depth: Bralon Addison is back, but the Ducks will need to find players to replace Josh Huff, Daryle Hawkins and De'Anthony Thomas in the passing game. Keanon Lowe will likely jump into the No. 2 role, but after that the pecking order is unclear.
OREGON STATE
Spring start: March 31
Spring game: May 3
What to watch:
Garrett steps in: There won't be any major philosophical overhauls under new offensive coordinator John Garrett, but new twists are inevitable. He and fifth-year senior quarterback Sean Mannion will spend the spring getting on the same page.
Revitalized running game? Running backs Terron Ward and Storm Woods will have to be more involved as the Beavers pursue greater offensive balance. Chris Brown's development will be important to add depth at the position after he saw scarce playing time as a redshirt freshman.
Replacing Crichton: Receiver Brandin Cooks isn't the only big-name player leaving Corvallis; finding a replacement for defensive end Scott Crichton will be just as important. Lavonte Barnett and Jaswha James are two players to keep in mind at the spot opposite Dylan Wynn, while defensive tackle Jalen Grimble should immediately contribute on the line as well.
STANFORD
Spring start: Feb. 24
Spring game: April 12
What to watch:
RB by committee? After Stanford's first spring practice, coach David Shaw touched on how it might become a running-back-by-committee in the Stanford backfield. He said it last year too, but without an experienced ball carrier on the roster, it rings truer this time.
Reloading on defense: The Cardinal had four defensive players at the NFL combine and also will replace first-team All-Pac-12 defensive end Ben Gardner. OLB Kevin Anderson, S Kodi Whitfield, DE Luke Kaumatule and ILB Blake Martinez are four players fighting for a chance at more playing time.
Staff changes: The program faces the most staff turnover in Shaw's tenure, with defensive coordinator Derek Mason (head coach, Vanderbilt), quarterbacks coach Mike Sanford (offensive coordinator, Boise State) and inside linebackers coach David Kotulski (defensive coordinator, Vanderbilt) all taking promotions elsewhere. Spring will be an important time to bring new coaches Lance Taylor and Pete Hansen -- and a third yet to be hired -- up to speed.
WASHINGTON
Spring start: March 4
Spring game: April 19
What to watch:
Petersen era begins: Chris Petersen's arrival to a major conference will be a national story line heading into the 2014 season. After posting a 92-12 record at Boise State in eight seasons, expectations are high in Seattle, where he'll replace Steve Sarkisian.
Status of Miles/Stringfellow: Quarterback Cyler Miles, who was expected to take over as the starting quarterback, and receiver Damore'ea Stringfellow were suspended indefinitely on Feb. 6, leaving questions about their status with the team. With Miles away, Jeff Lindquist and Troy Williams will get more opportunities.
Replacing Sankey: Jesse Callier, Deontae Cooper and Dwayne Washington will all compete for carries with Bishop Sankey off to the NFL. That much is clear. How the offense will use the trio isn't, thanks to the arrival of Petersen.
WASHINGTON STATE
Spring start: March 27
Spring game: April 26
What to watch:
Secondary turnover: The Cougars will replace three members of their secondary in cornerbacks Damante Horton and Nolan Washington and safety Deone Bucannon. Spring will be important for the potential replacements that include safeties Isaac Dotson and Darius Lemora and corners Daquawn Brown, Charleston White and early-enrollee Marcellus Pippins.
Bruggman watch: There's a lot of buzz in Pullman about backup quarterback Tyler Bruggman, who redshirted in 2013. While he's not expected to challenge incumbent Connor Halliday for the starting job, his development will be monitored closely.
OL makeover: WSU needs to replace the right side of its offensive line and center Elliot Bosch. Left tackle Gunnar Eklund and left guard Joe Dahl return, while Riley Sorenson, Jacob Seydel, Devonte McClain, Cody O'Connell, Sam Flor and Cole Madison will compete for jobs.
