Well I'm not exactly in "the know" for this particular incident but you don't have to look to Iowa to find this kind of stuff. I thought it was quite funny because everything mentioned in your post except for the "5 on 2" was performed in one of my matches this year by both me and my opponent, now I don't think that I have bad sportsmanship but sometimes people get caught in the moment and stuff happens. But as I mentioned before I was not there and not in "the know" for this incident in Iowa.
