My "curve" is based on not getting clearly out coached except rarely, and not getting mysteriously upset by very inferior teams. Richt obviously had problems beating Florida which was one issue, his teams lost twice to Tech at home, there was just these mysterious and predictable let down games, like losing to mediocre Tennessee badly and South Carolina with perhaps his most talented team. These are not things that happen to Saban or Meyer coached teams.
One thing about Dooley was his teams very rarely were upset, and they occasionally pulled off a major upset. They were tough teams, in the main, and usually not all that talented. Since about 2002, UGA has had talent to burn and weird seasons, like this one. They did have some decent wins but they almost looked bad winning them.
