sorry but yes I meant UNS, CNS is a French abbreviation. So it's not an unsportsmanlike conduct but a personal foul.
No, not a personal foul - a “Non-Contact Foul.” This is a foul for simply forming the wedge, irrespective of any subsequent contact with an opponent. So, since it doesn’t require contact, it can’t be called a personal foul. They didn’t want this to count against a player as an unsportsmanlike conduct foul, so, it is called a “Non-Contact Foul.” The signal is #27, which, these days, is labeled Unsportsmanlike Conduct. Some time it ago, that signal was labeled Unsportsmanlike Conduct/Non-Contact Foul, and, before that, it was just Non-Contact Foul. So, don’t let the label of the signal confuse things.
