I also read rumors that Shane Beamer might be a candidate at some small school in Virginia. Whether that's the case or not I don't know. The question is he's probably going to make a million dollars or close to it at UGA. Can UTSA match that kind of money. It is a head job though.
According to the link below, Hal Mumme and Craig Naivar, Houston co-DC are serious candidates. No mention of Mel Tucker, but I assume DawgNation has their sources.
