Bill Curry was a very good offensive lineman, center, when he played at Georgia Tech. He was a good player in the NFL, too. He has a great knowledge of the game, imo. His personality did not seem to be that of a great motivator, and I question his leadership skills as a head coach.
He was an assistant in the NFL before returning to his alma mater and was head coach at Ga Tech for 6 seasons in the early 1980's, only half of them with a winning record. He then became the head coach at Alabama for 3 years where he was successful, but lost to Auburn all 3 games. Disgust in the fan base and a modified contract by the administration led Curry to accept the head coaching job at Kentucky in 1991. During 7 seasons in Lexington, he only had one winning season, and had a 1-10 record in 1984, the worst in Kentucky history.
I think his teams at UK had some good players, just not a lot of them on the same teams, and he appeared to misuse the ones he had. The most-told explanation of why he failed with the 'Cats is attempting to force Tim Couch to run the option. Clearly, Couch was a great QB with talent who was essentially wasted under Curry.
