End of season brings several Pac-12 coaching changes

There were quite a few announcements around the Pac-12 on Monday. Allow this to catch you up:

Arizona: Coach Rich Rodriguez announced that defensive coordinator Jeff Casteel, who also coached the team’s linebackers, and defensive line coach Bill Kirelawich were dismissed. Both coaches, who have had professional relationships with Rodriguez for over a decade, were under contract through June 30 and signed their most recent extensions just before training camp started.

During conference play, the Wildcats ranked No. 10 in the Pac-12 in both yards allowed per play (6.29) and per game (484.6) and No. 11 in scoring defense (40.3 points per game).

Arizona State: The Sun Devils are expected to add Middle Tennessee State receivers coach Kodi Burns as the school's running backs coach, according to a report from Sports Illustrated, which also reported ASU tight ends coach Chip Long will leave to become the offensive coordinator on former ASU offensive coordinator Mike Norvell’s staff at Memphis.

Oregon: Two days after the Ducks blew a 31-0 lead to TCU, Mark Helfrich demoted Don Pellum from defensive coordinator to linebackers coach in a move that had to happen. Pellum has been on staff since 1993 and Helfrich gave him a shot following longtime coordinator Nick Aliotti’s retirement two years ago, but it clearly wasn’t working.

The Ducks had the third-worst scoring defense during Pac-12 play (37.8), ranked No. 7 in yards per play (6.1) and No. 11 in total defense (488.3).

"Don is a great man who has helped shape the culture and growth of Oregon football in several different capacities for nearly 30 years," Helfrich said in a statement. "He's committed, as we all are, to being part of the solution to improve the end results on the field."

The Ducks also announced that junior receiver Bralon Addison will enter the NFL draft and outside linebackers coach Erik Chinander is leaving “to become the defensive coordinator at another FBS institution,” which, according to several reports, is Central Florida, under former Oregon offensive coordinator Scott Frost.

Stanford: Junior tight end Austin Hooper declared for the draft. He caught 34 passes for 438 yards and six touchdowns, and was a first-team All-Pac-12 selection and a finalist for the Mackey Award.

USC: Tyson Helton (running backs and pass-game coordinator) and Neil Callaway (offensive line), both of whom were at Western Kentucky in 2015, were officially added to the coaching staff.

Helton, the younger brother of head coach Clay Helton, was the Hilltoppers' offensive coordinator and quarterbacks coach, and Callaway coached the offensive line. Callaway also previously served as the head coach at UAB and as offensive coordinator at Houston (under Helton's father, Kim Helton), Alabama and Georgia.

“We are very excited to welcome Tyson and Neil to the Trojan family,” Clay Helton said in a statement. “Their experience and knowledge will be a huge benefit to our players as well as our football program.

“Both have been highly successful coordinators and we look forward to the fresh energy and ideas they will bring. I have watched them produce a pair of top-10 offenses that averaged more than 44 points a game each of the past two years. We look forward to them helping bring the same explosiveness to our offense at USC.”

Utah: Defensive coordinator John Pease, 72, has retired for the second time. He will be replaced by Morgan Scalley, who served as the Utes’ recruiting coordinator, special teams coordinator and safeties coach.

“We appreciate the passion, energy and coaching expertise that John Pease brought to our program on a daily basis,” Utah coach Kyle Whittingham said in a statement. “While we completely understand his decision to retire, players and coaches alike are sorry to see him leave. Through the years, John has had a major impact on Utah football as a player, coach and longtime friend and advisor.”

Whittingham lured Pease out of retirement for the second time last offseason and the results were outstanding. In conference play, the Utes ranked No. 1 in the Pac-12 in yards allowed per game (365.3), No. 2 in yards allowed per play (5.16) and No. 2 in scoring defense (23.0 points per game).

Washington: The Huskies announced quarterback Daniel Bridge-Gadd, defensive back Taylor Rapp and defensive lineman Myles Rice all enrolled in school and are officially part of the program.
