So far, only three Pac-12 teams retained their 2013 offensive and defensive coordinators: Arizona, Colorado and Washington State.
Here's a look at who's in, who's out and what it means in the South Division. You can review the North Division here.
No change: Rich Rodriguez has proven coordinators on both sides of the ball, with the offensive humming under co-coordinators Calvin Magee and Rod Smith and the 2013 defense being the Pac-12's most improved unit under Jeff Casteel.
Out: Cornerbacks coach and special teams coordinator Joe Lorig left for Utah State, which allowed coach Todd Graham to rejigger his defensive coaching staff. Paul Randolph, a co-defensive coordinator the past two seasons, will serve as senior associate head coach and defensive ends coach.
In: Keith Patterson left West Virginia to co-coordinate the defense with Chris Ball. Patterson will coach linebackers and be the Sun Devils' defensive special teams coach. Ball will continue to serve as the safeties and defensive passing game coach.
Thoughts: A lot of these moves emerged from Graham's concern about special teams, as well as his wish to reunite with an old friend. He and Patterson, according to the press release announcing the hiring, "have a professional and personal relationship that goes back to East Central University where they were college roommates." That same press release noted that "Patterson will oversee the defense, but Graham will be heavily involved in the planning." Graham also will have a "major" role with the special teams coaching and will assist Ball with the cornerbacks. It was also announced that Chip Long, the Sun Devils tight ends coach and recruiting coordinator, will become the offensive special teams coach. As for Patterson's track record, it was a lot better at Pittsburgh than at West Virginia, where the Mountaineers allowed 33.3 and 38.0 points per game over the past two seasons.
No change: Colorado's second-year coach Mike MacIntyre retained both defensive coordinator Kent Baer and offensive coordinator Brian Lindgren. Compared to 2012, the Buffaloes scored 7.6 more points per game and allowed 7.8 points fewer per game last season. The overall numbers weren't good, but it was clearly a step in the right direction on both sides of the ball.
Out: Defensive coordinator Lou Spanos left to become the LBs coach for the Tennessee Titans
In: Jeff Ulbrich was promoted from LBs coach and special teams coordinator.
Thoughts: Ulbrich has coached perhaps the Bruins most improved position over the past two years -- linebackers -- and he deserves credit for players like Anthony Barr, Jordan Zumwalt, Myles Jack and Eric Kendricks developing into stars. He also ensures the Bruins improved defense retains schematic continuity. Named the 2013 FootballScoop Special Teams Coordinator of the Year, Ulbrich has guided the Bruins special teams unit to one of the top rankings in the country in each of the last two seasons. Ulbrich also won't have to work too hard to have credibility with his players as he was a LB San Francisco 49ers from 2000-2009.
Out: Defensive coordinator Clancy Pendergast
In: Justin Wilcox, who followed new Trojans coach Steve Sarkisian from Washington to USC
Thoughts: Sarkisian decided to retain USC offensive coordinator Clay Helton, though like his predecessor, Lane Kiffin, Sarkisian will call offensive plays. Pendergast did a great job last year with his hybrid 3-4, which he termed a 5-2. Wilcox is widely seen as one of the nation's top defensive coordinators and a future head coaching candidate. His scheme won't be too much different than what the Trojans ran last year, though the Huskies officially ran a 4-3.
Out: Co-offensive coordinators Dennis Erickson and Brian Johnson were demoted to running backs and quarterbacks coaches, respectively. Johnson then left Utah to become Mississippi State's quarterbacks coach.
In: Former Wyoming head coach Dave Christensen was hired to be the Utes’ single offensive coordinator
Thoughts: Will Christensen bring the Utes offense stability? He's their sixth different play caller in six years. The good news is he's highly regarded, getting hired at Wyoming because of the work he did with Missouri's offense. Johnson's departure probably helps reduce the feeling that there are too many cooks in the kitchen, seeing that he, Erickson and Aaron Roderick, now the Utes QBs coach after coaching receivers since 2005, have each been in the coordinator carousel at Utah. Head coach Kyle Whittingham also hired former Purdue All-American Taylor Stubblefield to coach receivers. Christensen, an offensive line specialist, will oversee tight ends.
