I've played BB for a long time, and I've never seen anything like this. It seems pretty absurd, but my opponent argued that because there was nothing in the rules (LRB3) to specifically prevent him from doing it, then he was allowed to. I got fed up arguing (something about a brick wall). He also spent three turns camped next to my endzone before scoring from one square away, so you probably have some idea of what kind of player he is. Still won, though.

Thanks for the help.
