So, what difference to herd health does it make if the buck is 1 1/2 doing the breeding or 6 1/2?
That buck has the same genetics form birth to death..

1) The 1.5 year old has a better chance of surviving in good health if he doesn't have to undergo the rigors of the rut. (this benefits both the individual and the herd) 2) The 6.5 year old has proven himself, while the 1.5 year old hasn't. (benefits the herd)

Because a mature buck that is breeding has proven his genetic capability through whatever Natural Selective process that Nature is using. Not every mature buck is a breeder. That means Nature is using some selective process, and anything Nature is selective for that is heritable will then be passed on at a higher rate than less desireable genetics. A yearling buck is too young to have expressed his genetic potential yet, hence Nature has nothing to select for.
In addition, Nature did not intend yearling bucks to be regular breeders. Breeding is extremely stressful on bucks. Even in balanced sex ratio herds, breeding bucks can lose 25-30% of their body weight during the rut. A mature buck can withstand that and it causes no "developmental" harm because he has finished growing his skeletal structure long ago. A yearling buck is still growing his skeletal structure. If much of his body weight is burned away during the rut, nutritional intake in spring will be used to replace the lost body weight instead of being used to continue growing larger. Yearling bucks that are heavy breeders (in herds with poor sex ratios or poor buck age structures) often become stunted body-wise, and that stunting lasts for life. With most mammalian species, and especially deer, body growth opportunities lost early in life are lost forever.

how did they know that "inferior antler genes" were expressed if this DNA study was done on dead fetuses? I have never agreed with the results of this study and find it complete BS.
