Once again, it's not strictly a zone defense. Every team has sprinkled in aspects of man to man and zone in their defensive philosophy. There is not one NFL team that is strictly a zone or man-to-man defense. Is our base defense based (no pun intented) on the zone, yes; but that has no bearing on whether or not man-to-man is also used.
Correct. But we run zone because it's our scheme. Not because we don't have the talent. I suggest you do some research on the Jim Johnson 43 and come back here
