When West Virginia athletic director Oliver Luck left the Mountaineers to accept a position with the NCAA last week, it triggered speculation that WVU will hire alumnus Rob Mullen for the vacancy. Mullen is the AD at Oregon. If that happens, the dominoes will continue to fall, and Arizona’s Greg Byrne would surely become the first name mentioned to be AD at Oregon. Byrne grew up in Eugene and later worked for the Ducks. His wife, Regina, is from Junction City, a small town 15 miles from Eugene.
