We should be happy the PA Game Commission allows a junior hunter to take any buck, regardless of antler size. To me, increased opportunities for youngsters, 16 and under, will keep them interested in hunting.
I'm 52. When I was 12 or 13 years old, hunting in PA, I would have been disappointed if I had seen a small buck and had to pass due to antler restrictions. With years of experience under my belt, I'm happy to pass on small bucks now, knowing more chances will come.
There are definitely bigger bucks in PA since the antler restrictions were implemented, and the few small bucks taken by youth hunters does not significantly impact the population.
