Are you familiar with Boxing? They both train and fight in the clinch up until one guy wraps both arms around an opponent at which point the ref will separate them. "Fight your way out" is the refs command when fighters have a single collar tie clinch.
This is all irrelevant though since I've only been talking about the situation and range in the video in which case you can say with 98% certainty that Conor would have been knocked unconscious before he would have any chance of throwing a kick, shooting a takedown or landing knees and elbows in the clinch.
This is by far the most pointless argument I've ever had but I will admit it is rather amusing hearing all your reasons why an MMA fighter couldn't possibly lose a close quarters fight against someone who isn't a "fighter" because he only trains to knock people out using his fists, lol.
