No, he didnt. In 91, Vandy beat Ole Miss (30-27), Kentucky (17-7), and a 9-3 GEORGIA team (27-25). In 92, Vandy beat Kentucky (20-7) and a 9-3 Ole Miss team 31-9. Kentucky was the only 93 SEC victory (12-7), but, in 1994, DiNardo beat Georgia again (43-30) and Kentucky again (24-6). By Vanderbilt standards over the last 60+ years, DiNardos overall records were not bad: 5-6, 4-7, 4-7 and 5-6. See Vanderbilt Historical Scores.
And those are some damn low standards....
