Stationary elbow: player rebounds and "chins" the ball, elbows extended but not moving or pivoting. A moving opponent contacts the elbow.

By NFHS direction, this might be incidental or a common foul. The rationale for calling a foul here is much the same as calling one on the player who has his legs wide on the floor: he's exceeded his legal spot on the floor and the vertical space above it. Rule on whether the opponent is disadvantaged by the contact.

As I understand the direction, elbows moving with the hips in a pivot and making contact above the shoulders is an INT. Elbows moving faster and making contact above the shoulders warrants a flagrant foul.

I have called several "excessive swinging" violations so far this year, and in each case the coaches seem to be aware of the new guidance and why I'm calling the violation.
