I'll go with Arkie. They lost 19 straight SEC games and Pittman comes in in year 1 and beats Tennessee in Pruitt's third year. What makes me think this is the worst loss is that Pruitt griped about how talentless Tennessee was in his year one, yet Pittman (who had less talent than we did in year 1) comes in and shows how a coach needs to figure out how to get his team to buy in and win with what you got. You won't beat the Alabamas and Georgias with less talent but you convince your team in year 1 that they can win the winnable games. Pittman has done that, Pruitt hasn't.
