The criteria is kinda narrow, isn't it? I mean, how does winning a few WAC titles define Dan Hawkins as "great"...yet a Mack Brown who has lost one game in his last 30-something games, won a conference title and a national championship fall short of "greatness"? Mack's cheesy, but dude has consistently won, period. BTW, Spurrier is the coach I respect the most. Anyone who can win at Duke----Duke!---is definitely "great" in my book.
You may be right. Greatness was probably a bad choice of words, but I greatly admire a coach that can go into a program, that isn't a national power, and start dominating the competition as he did.
