Judging by the neck-to-brisket and the belly sag, my SWAG is 5.5 or older. Not the best pics to judge with, but that's my story and I'm sticking to it.
I would say 5.5, but I can’t tell anything from your last years picture. And I also agree that the picture could be a little deceiving. Neck does connect with the brisket and the picture is from early October. When is the rut there?
