I think Poirier took McGregor lightly in their first match. It was still early in McGregors UFC career and he hadnt yet proven himself to be a serious threat. Poirier got caught, and finished, but I doubt it would happen in a rematch. He is also much better at 155, and has matured as a fighter. If McGregor ever actually fights Ferguson, after he loses I'd like to see a rematch with Poirier at 155. Thoughts?
