It happens at the 1:35 mark. Again, to me, this is a no-brainer. After the foul call, he appears to either look right at the official who made the call, or in the general direction of the fouler, and spikes the ball hard. Easy call and no hesitation from the Lead.
As for the delay, a ball spiked that hard could go anywhere. Granted in those arenas, they have plenty of people to retrieve the ball quickly.
