I get that the velvet would have to die off, but the antlers are firm enough all mating season for battles, why not keep it year round? I think I may have a theory: deer antlers evolved to be too elaborate to maintain all year without hindering the animal's survival. Antlers can get caught in brush and trees when fleeing from a predator and prohibit escape through tight spaces. Horns on prairie / savannah creatures like bulls, ox and buffalo prob do not have to worry as much about fleeing through densely wooded environments. I suspect it also ensures the males will cooperate when not "in the rut".
