Just because you get put in a choke hold that doesn't mean you were anywhere close to tapping. We have seen Ben Henderson in that position many times.
He maintained his composure and recovered really fast hardly something you ever see from someone who was nearly finished.
First, he got hurt standing!
Second, that choke was fucking tight. He gutted it out and it actually gave him time to recover. Have you ever been in an arm triangle? I am good with that choke hold and it looked tight. Props to Johnson for not tapping, but it was close.
