Hard to say but did he say he set any specific goals of deer size at the beginning of the hunt? Maybe that deer was on the borderline of what he hoped to take, hard to say. I have been there when I am faced with only one week of hunting. To me if it's mature and meet's our guidelines I would be happy to tag it. There are times when I would pass a deer that I shouldn't have, thinking there were better opportunities at bigger and by the end of the week I am kicking myself. If not on his part, yeah he likely should have let it walk but hey, who are we?!?! LOL!
