Spurs Get Lucky Break From The Shot Clock

So this was weird. Earlier in this possession, Russell Westbrook deflected a pass into the backcourt, but Danny Green of the Spurs ran it down and allowed San Antonio to retain possession with four seconds left on the shot clock. The Spurs didn't know it and were all set to get called for a violation.

But that was before the shot clock randomly reset to 24 for some reason.

Divine intervention? Conspiracy? Only the eye in the sky knows.
