That goes without saying that Billy Gillispie is the current coach of University Kentucky Wildcats...although he does come from the Adolph Rupp coaching tree given that he was an assistant to Bill Self (at Tulsa and Illinois) and Self was an assistant at Oklahoma State University under Leonard Hamilton. Hamilton was an associate head coach at UK under Joe B. Hall, who both played and served as an assistant for the Baron, Adolph Rupp.

I'll update this again when LSU and USC name their new basketball coaches but out of the twelve programs in the conference, six have definitive ties to the state while one's coaching tree has Adolph Rupp in it.
UPDATE: I've updated this now that Darrin Horn is the new coach of USC.
