Luke was there 3 seasons, and he totaled 15 wins in that time frame. Freeze was before him with 24 wins in his first 3, and lasted longer meaning more total as well - he had 34 in 4 years. Before freeze was nutt, with 22 in 3 years and more total. Cutcliffe had 21 in his first 3 with more total, and Tuberville 19 in his first 3 with more total. The only coach in the last 25 years that was worse than Luke was Ed O.
Even if you take away a lot of freeze's and Nutts wins due to the NCAA vacating them, freeze still has 10 wins in one season not vacated. So 10 in 1 vs 15 in 3 lol. The 2 seasons that Nutt didnt have taken away also still eclipse Lukes 3 seasons as Nutt had 18 wins in 2.
