I think there are 14 seasons w/ 8+ wins post Dodd (guessing you didn't count 1970 as post Dodd era?)
by decade:
70s: 1 ('70)yeah must’ve missed one , but I guess my point is it’s not easy winning here
80s: 1 ('85)
90s: 4 ('90, '91, '98, '99)
00s: 5 ('00, '01, '06, '08, '09)
10s: 3 ('11, '14, '16)
by coach:
Johnson: 5
O'Leary: 4
Ross: 2
Gailey: 1
Curry: 1
Carson: 1
Six of GT's nine coaches since Dodd had at least one 8+ win season. Only two (Collins and Lewis) did not have a single winning season. Pepper Rodgers posted 8+ win seasons at Kansas & UCLA, but never got above 7 at GT. Curry, Lewis, and Collins are the only three below a .500 career mark at GT post Dodd. Lewis was a little below .400 when he was replaced mid 94. Curry and Ross both won fewer games than Collins their first two seasons, but both posted winning seasons their 3rd year. Collins is currently .294 (10-24), which is 10+ percentage points below Lewis's and Curry's GT career marks.
