Then how about this. You take the court with 15 minutes before start time. You immediately notice a kid in a red jersey with a white undershirt. When he ends up in the layup line closest to you, you approach him and tell him that undershirt is illegal, and he needs to return to the locker room to remove it. WIth about 12 and a half minutes still on the clock, he heads over to the bench, removes his jersey, removes the illegal undershirt, replaces the jersey, and continues to warm up. Do you whack him for this?
