We won before. We didn't need to "change anything to win."
Bobby Ross, even with 2 horrible transition years, went 31-26-1 in 5 seasons with 2 wins over UGA, an ACC championship and an MNC.
George O'Leary went 52-33 in 7 seasons with 3 wins over UGA, an ACC championship, and Gator Bowl win over ND.
Chan Gailey, the worse of the four, went 44-32 in 6 seasons with 0 wins over UGA, a divisional champ, and an ACC championship game appearance.
Paul Johnson went 82-60 in 11 seasons with 3 wins over UGA, an ACC championship, 2 other ACC CG's, a Gator Bowl win, and 2 Orange Bowls.
Those four coaches, from 1987 through 2018 (32 seasons) were a combined 209-151-1, with 8 wins over UGA (not good!), 3 ACC championships, 3 other ACC CG appearances, 2 Gator Bowl wins, 2 Orange Bowls, and an MNC.
Now... tell me again why things had to change to win....
I'll hang up and listen.
