I wont argue that he big and mature, but I doubt he is going down hill. usually the horns will look real blunt and blocked off and his look sharp and bladed. he is pretty. We have a buck on cam we call "squatty" we have pics of him for 3 years now. The past 2 he has been a big bodied 6 pointer with a small rack with his tines turning inward, and we all thought he would be a good one for the kids to shoot. Well this year he is even fatter and his rack has that same shape but he now sports 10 points and its a really unique rack. I say this because the buck in your pic looks like him last year.
