I know Barrett and Mills personally, I like them very much. I attended Barrett's wedding and have know him for 18 years. He and Mills are excellent trainers.
Neither one of them (I am sure) would agree with you that they were the only successful coaches, along with Talbot, in Greeneville. I doubt they would even agree that they "dominated" Giles.
2001? regional champions = Hyslop (though everyone had a hand in on that. Mills, Rinker, Barrett)
2003 regional semifinalists = Hyslop (again, the entire staff contributes)
I think a semifinal appearance and a title at regionals in three years qualifies as successful, maybe I am crazy though.
P.S. Sorry you had to wait for my reply.
