Leave those little buck alone, they will grow up and at this point you don't know about their genetic potential. He may have the best potential for the biggest antlers ever, but you don't know it yet. Also the messed up bucks someone spoke of may have sustained an injury this year that will go away in future or it might someday be a huge nontypical. You don't know yet. Nature has a way of working things out, but after 3-4 years and still no antlers, cull them.
