I think he was worried about the size/power. I had it pretty close though 48-47 Poirier. Holloway might have been able to take it if he had eased into 155 a bit more. Had a warm up fight or two.
There was nothing clear to strikes landed, stats have max landing more in total, yes Dustin hits harder and made it look like he was landing more, that doesn't equate to the OP's question, about who is the smartest. http://ufcstats.com/fight-details/87126427cfcaee52
