Where have all the Pac-12 assistants gone?

Several Pac-12 programs will have new faces patrolling the sideline (or coaches’ boxes) at coordinator positions this spring and next fall, but there also has been even more movement under those coaches at several of the assistant positions.

Every school but Stanford has made notable changes in its position coaches.

Here’s the full list. But a quick note: In-program moves aren’t detailed (e.g. Oregon’s Matt Lubick, Washington’s Jimmy Lake, Utah’s Morgan Scalley) and USC’s coaches are noted for the staff heading into the bowl season. The rest are from the beginning of the 2015 season.
