I love seeing a pic like this. After they have been running at their peak for a while, you get to see a true buck's maturity. Take a look at the chest on that fella! Even though he is looking skinny, you can see his mature shoulders, chest, and hips thatwe all look for in a buck. I have always preferred to look at a buck's chest and broadness of shoulders to determine true maturity. Sagging bellies and sway backs can tell me just so much. I also pay a lot of attention to his head size and forehead hide. Just as with us guys, they get a little discolored on top of their heads the older they get too. This buck has it all in my opinion. Best of luck with him! He will only provide that sort of opportunity for a very slim amount of time.
