Foster made a comment in an interview with AL.com that he would go where ever Trooper went. Here's betting that you see Trooper hired by Georgia within the next few weeks. Here's a different article, but basically saying the same thing.

I'm not so sure he's hireable with the NCAA microscope that would be coming with him, not to mention that he can't develop the talent he brings in. I do think Foster ends up at UGA but not anything to do with Trooper.
