Here's an interesting bit: Although not real clear, it seems the "ninja" in this video of an MMA cage bout ended up the winner.
And one reason it's not real clear is that what technique is visible does not appear to be classic taijutsu. Of course, HWSNBN has said all along that "real" fighting won't look like practice. (Although he also says MMA isn't "real" fighting because both people start and end fully expecting to go home at the conclusion of the pre-arranged match, and there is no possibility of one or both fighters pulling out weapons, and... oh, you get the point.)
Another reason is that no one who posted this really bothered to identify the fighters. So why do I make the educated guess the "ninja" is the winner? Because it seems to be posted by one of the To Shin Do Quest Centers, and why would they post a loss?
Something for you all to mull over. Draw your own conclusions.
