Is that an RNC or an RNC variation?! The distinction is not trivial!!
Standard Rear Naked Choke applies pressure at the carotid arteries โ blood-flow restriction. Some RNC variations contact the lower mandible, introducing tracheal compression alongside arterial pressure. The physiological mechanism differs. So does the risk profile and the stoppage logic.
Stoppage timing was correct โ fighter tapped. Not a referee issue. The problem was commentary using both terms interchangeably for 20 minutes. Misrepresenting technique to 500,000 viewers is a disservice to the sport. Precision in terminology is respect for the craft.
