Interesting video. I have always defined combinations differently. Although they did combine punches. Just, to me if you pause to assess it is not a combination. And then many I would call putting punches together, punches in bunches or flurries.

To me a combination is punches that are designed to work with each other. Not just right-left-right-left. But that's boxing, so many different ways to speak of it. By what I call a combination only about 5 of those were. #17, LL, Tyson, can't remember which others.
