His defensive strategy was copied, many times, and still being used as a model, today. Just look at LSU and Bama. It was really very simple. Put two huge run stoppers, at DT (Henderson, Haynesworth, etc), force everything outside, so your fast LB's could run it down. DE's were pure pass rushers, with motors that never quit. We played a lot of two-deep zone, with the safeties, and mixed up coverages with the corners. Overall, the defense was aggressive, and tried to force turnovers, giving the offense more opportunities. When Chavis had depth, at the LB and D-line, his defense was tough to handle. Especially when coupled with a balanced offensive attack like Cut's. The kicking game was huge. Pinning offenses deep, and putting pressure on them, forcing them to drive the length of the field, turn it over, and make mistakes. All phases complimented each other. We need that now.
