Well if you aren't a sports guy than I'll explain what a foul shot is. It's when you get fouled and go to shoot 2 freethrows no one is guarding you when you shotand your exactly 15 ft.away from the basket . This type of shots is a shot that could make you win a game or lose a game. Now I thought if a player is shooting a freethrow in an arena you know that everyone is surrounding the basketball court. I was thinking that if everyone from one side of the arena exhailed or blow out all at once that, I thouth that might have an effect on the shot. It was just a thought thanks.
