Since I'm a Coues's deer virgin, I can't speak for them. However, Mulies that I've taken pre, post, or during the rut have not tasted badly. Amanda hit it right on the head. Its all in how the meat is cared for. If you get excretions or hair from the tarsal glands on your hands or knife and then on the meat, it will taste just like the tarsal glands smell. Take care in how you handle the meat and it will pay off at the table.
Good hunting!
