How NBA Refs Are Trained to Judge the SGA-Fox Foul (The Mechanics Explained)

Most fans arguing about the Fox-SGA foul have no idea what refs are actually trained to look at.⁣
⁣
The covering official had to position adjust just to keep an angle between two moving players. Then it's up, down, rebound — eyes follow the shooter up, check elbow and wrist contact, track all the way back to the floor for lower body, then check landing space for a reckless closeout. All of that happens in real time.⁣
⁣
And you could see the ref crane his neck around the corner and point out exactly what he saw. He had it the whole way down.⁣

NBA refs catalog hundreds of abnormal motions in preseason and recall them on the fly in-game. The consistency on jump shot contact calls is actually really strong. The one-offs happen, but they're not the norm the way fans on Twitter make it seem. #shorts
