While I agree that gentics is important, age and availablity to quality food are more important to good antler growth. In their early years, most of the nutrition a deer takes in goes towards development of their body before their antlers. What confuses me is that the deer in the pic obviously had quality food to grow that rack, but why only 92 lbs. I don't think that you would even be able to find a deer in Indiana that had the smallest of racks that would not go 110 to 120. Most of our button bucks go 100+.

Genes alone don't grow quality antlers. Those genes need fed. I'd be concerned about the fact that that deer did not weigh anymore then he did.
