Conor McGregor's fight with Dustin Poirier at UFC 257 this weekend may be a rematch but it is not your average UFC sequel - and Poirier is not your average fighter.
It's no grudge match, there's no bad blood, and it's not like there's any unfinished business - McGregor was a clear winner when they last met in September 2014.
