No you wouldn't be DQ'ed....when it says the WHOLE deer, it means just like Tim said. They don't want to see a caped out buck, or just the skull plate with the antlers on it. It's really quite simple and shouldn't be blown out of proportion...just take a good picture with the deer (preferably before gutting), yourself, and YOUR BOW. There was actually a person last year that got caught trying to enter a gun kill in this contest, and like Tim said I wouldn't be surprised to see someone try to enter a roadkill even.
The rules are the same for everyone, and again like Tim said there were several other pictures of the deer posted in the general bowhunting area with the story. I'm not sure if they got the giant on film, but I think they got the other on film because those guys actually do make their own hunting videos so yeah...the kills were well documented and without question.
