Im not sure what you are saying now, but Ill try. What Im saying is, too many deer makes for lesser quality deer. Dominant bucks breed, and of course, to some extent so do most of the other bucks. But the best does cycle and stand for the better buck, natural selection touches on this. The lesser bucks can still have the similar DNA as theyre most likely related to the dominant buck. Lower herd numbers just helps insure that the healthier better, and in theory, "trophy" bucks do the majority of the breeding. Antler restriction rules on the other hand, are just insuring that the buck, regardless of what potential he has, lives long enough to make an attempt to reach that potential. I believe they use antler restrictions simply because the average laymen hunter isnt able to field judge deer for age. Its difficult for most, especially in a hunting situation.
