Since their first meeting at UFC 178, 'The Notorious' Conor McGregor and 'The Diamond' Dustin Poirier have gone on incredible runs, leaving championship calibre fighters in their wake and winning 3 titles between them.
Conor McGregor winning the interim UFC Featherweight Title, knocking out Chad 'Money' Mendes, Knocking out 'Scarface' Jose Aldo to win the Undisputed Featherweight Title and Knocking out 'The Underground King' Eddie Alvarez to win the Undisputed UFC Lightweight Title.
Dustin Poirier himself has since finished former Undisputed UFC Lightweight Champion Anthony 'Showtime' Pettis, finished former Undisputed UFC Lightweight Champion 'The Underground King' Eddie Alvarez, and Dominated then (and still in the eyes of many) Undisputed UFC Featherweight Champion Max 'Blessed' Holloway in their rematch.
On January 23rd, at UFC 257 the two will meet again. The Flow of Water vs The Violent Burning Flames. Remains to be seen, whether it will be reassurance or redemption.
