How Gaethje set up his head kick against Poirier

I'm going to start posting video in the lead up to UFC 300, so why not start by looking back on Gaethje's sensational knockout of Poirier.

We saw recently that Poirier still has it, so that makes me appreciate even more the fact that Gaethje found a way to fight Poirier and it not turn into an all-out war.
