Stacy Searels was another OL coach under Richt at Georgia. He left to take a lateral job at Texas though and then was relieved of his duties after a few seasons. He is now at Virginia Tech as their OL coach in 2014 and 2015. He might be available due to the uncertainty with their coaches as well. I don't know anything about the relationship with Richt though since he left for a lateral job.
Before Georgia he was at LSU, so he knows big-time coaching.
Searels had four players drafted that he brought in (Clint Boling, Justin Anderson, Cordy Glenn, Ben Jones) and had four all-conference players during his time there (Boling, Glenn, Jones, and Chris Burnette). He also brought in Trinton Sturdivant and got him ready to start as a true freshman- becoming the first true freshman T to start opening day for Georgia. Knee injuries ruined his career. He also developed a player- Kolton Houston- who had multiple leg injuries, but was good enough to beat out 5-star OT John Theus who was benched for Houston. Theus was moved over to LT after another injury, but never did beat out Houston.
He would be my top choice if I knew anything about the relationship between he and Richt.
