During a freethrow shot in Basketball after a foul, players stand in front of the freethrow shooter. What happens if those players try messing with the freethrow shooter? Like yelling "BRICK" right as he shoots, or waving their arms like a lunatic, or doing some crazy tiktok dance, etc..
To be clear, I'm talking about non-physical meddling. And assuming that there's obviously a line that can be crossed (e.g. screaming "BLOODY MURDER" at the top of your lungs), around where is that line, and why don't we see players pushing up against it?
