We've all heard that an undefeated season in college football is more rare than a NC. We all know that Auburn has 3 in the last 18 years which puts us in rare company. But what about coaches? In the last 6 years, Gene Chizik has played a significant role in 3 Unbeaten/Untied seasons. Granted "only 1" as a HC, but I think you still have to wonder what he's learned about it, and how to make it happen. I don't have the time to find out how many these coaches were a part of as Asst. Coaches, but I think their HC records should shed some light on the accomplishment.
