Personally, I think we went away from the zone blitz the last couple of years. We went to the 3-4 over, and the rush was always the same 4 players. Clay, Daniels, T-Rex and Perry when healthy. It was always the same four. There was very little line 7 guys up near the line in your 3-4 and you had no idea which 3, 4, or 5 were coming.
Double A-gap blitz was the preference. Or slot blitz.
Bud Adams told me the franchise he admired the most was the Kansas City Chiefs. Then he asked for more hookers and blow.
