He's young...learn to ID age classes and harvest when they reach a certain age...trying to manipulate genetics in a free-ranging deer herd is next to impossible...that is something for high-fenced areas where they can keep less-than-desirable genetics out. ONE of those breeding deer in a population perpetuates the genetics...whether or not those are good or bad genetics should be up to mother nature to decide, IMHO. Since this particular buck is young, you wouldn't be able to tell for a couple more years what kind of genetics he has anyway.
