Colorado took its first significant swing in Pac-12 action, raiding Arizona's staff for two assistant coaches.
Co-defensive coordinator Greg Brown and defensive tackles coach Mike Tuiasosopo are headed to Boulder to join the staff of new head coach Jon Embree. The Arizona Daily Star reported neither is expected to stick around for the Valero Alamo Bowl against Oklahoma State.
Brown, a secondary specialist, was hired away from Colorado last year by Mike Stoops as co-coordinator with Tim Kish. Tuiasosopo was a member of Stoops' original staff in 2004.
