Well, let's take it a few steps further:
1966 9-2 Dodd
1967 4-6 Carson
1971 6-6 Carson
1972 7-4-1 Fulcher
1973 5-6 Fulcher
1974 6-5 Rodgers
1979 4-6-1 Rodgers
1980 1-9-1 Curry
1986 5-5-1 Curry
1987 2-9 Ross
1991 8-5 Ross
1992 5-6 Lewis
1994 1-10 Lewis
1995 6-5 O'Leary
IMO, a constant changing of coaches bodes well for no one. At almost every school you look at, changing coaches within 5-6 years impacts for at leasT 2 more years. I know that there are exceptions. Since 1966, the HCs at Tech have stayed an average of less than 5 years each. About half the coaches left of their own accord (Fulcher, Curry, Ross & O'Leary) and about half left otherwise (Carson, Rodgers, Lewis).
I think one thing that frustrates many is that Tech had apparently "gotten back" to where we wanted to be. For example, 5 consecutive bowl games (though none really a major); a winning pct. over the last 4 years that was the best 4 year winning pct. since Dodd stepped down (1963-66: 30-11-1, .726; 1998-2001, 35-14, .714)
