Since your in Indiana and he isn't in rut yet, I would say 4 1/2. He is starting to get some belly on him and when the rut starts, his neck will appear that it blends right into his shoulders. He's starting to get some mass to his bases and he definitely has multiple points for an older deer. His body isn't fully developed yet by looking at his long legs. As he ages, his legs will look shorter as he puts on weight and body mass. One more year and he'll be a STUD but you make the call, if he presents a shot.
