and, a tale from the opposite side:
I'm lead. Ball is shot, seems (in my peripheral vision) to "check up" and falls straight down. Bounces twice. 8 players head back to the other end of the court. B1 heads for the ball with no real sense of urgency. Grabs the ball and nonchalantly tosses it to B2 who hasn't moved much. B2 starts to dribble up the court.
I blow the whistle for a throw-in violation. Partner gently informs me that the shot was missed.
