LAS VEGAS -- Let's start off by establishing one thing: This isn't Conor McGregor's last chance at UFC championship relevance.
Let's say he were to lose to Dustin Poirier -- for the second time in six months -- at UFC 264 on Saturday inside T-Mobile Arena. He would definitely be in "the sky is falling" territory. If he loses, he will have lost three of his past four MMA contests, and four of his past five combat sports appearances overall (counting his 2017 boxing match against Floyd Mayweather).
At that point, the chances of McGregor ever attaining a UFC championship again will seem relatively slim.
