If that was a textbook flagrant foul, why wasn't McCormack's illegal screen on Kalscheur late in the game called a flagrant? He stuck his shoulder out and hit Kalscheur in the face.
A flagrant 1 foul (men's) or unsportsmanlike foul (women's) involves excessive or severe contact during a live ball, including especially when a player "
swings an elbow and makes illegal, non-excessive contact with an opponent above the shoulders". This offense includes the former "intentional foul" of fouling an opposing player to prevent an easy breakaway score. In women's basketball only, the unsportsmanlike foul also includes contact dead-ball technical fouls. The penalty for a flagrant 1 or unsportsmanlike foul is two free throws and a throw-in for the opposing team at the out-of-bounds spot nearest the foul.
Setting a screen is not excessive. He did not swing an elbow. He did not foul to prevent a breakaway score. It meets none of the criteria for a flagrant foul.
The ISU player swung his elbow during a live ball and made contact above the shoulders. Textbook definition of a flagrant.
