The only way I would have passed is if I had scouted that stand knowing that there was a 14 pt in the area and had pictures of him, otherwise he may not shoot a deer for 20 years with that rule.
That deer would have been down in a flash if it were me, but does your buddy have pictures of this 14 pt? Has he spotted him near his stand? If he is hunting A deer that he is aware of, I hope he nails him, otherwise I would question his sanity.
