Longer footage is widely available on the web, which might bring up issues regarding either 1) the difference between NFHS and NCAA-M signaling and subsequent upgrading of the foul to a flagrant (NFHS) or flagrant 2 (NCAA-M), or 2) whether or not the covering official, having turned his head toward the flight of the ball, saw the actual foul or reacted only to the outcome of the foul.
We're grateful he made the call which ultimately led to the correct adjudication. I'm only analyzing mechanically, and not purely critically.
