Manny Fernandez
The 3–4 defense was originally devised by Bud Wilkinson at the University of Oklahoma in the 1940s as the 5-2 Oklahoma defense. The 1972 Miami Dolphins were the first team to win a Super Bowl with the 3–4 defense, going undefeated and using number 53, Bob Matheson, as a down lineman or rushing linebacker. Matheson replaced defensive tackle Bob Heinz, shifting Manny Fernandez to nose guard.
