Herm Edwards’ coaching staff at Arizona State is reportedly losing one of its most important pieces.

ASU defensive line coach Jamar Cain is set to become the new outside linebackers coach at Oklahoma, per The Athletic’s Bruce Feldman.

Cain has a reputation as one of the best recruiters in the Pac-12 conference and was only with the Sun Devils for one season. That position has been a revolving door at ASU, as the replacement for Cain will be the sixth straight new defensive line coach.
