Any fight fan who spent time on social media in the past month or so has probably seen someone express the sentiment that they don’t want to see Charles Oliveira or Dustin Poirier lose on Saturday when the two face off in the main event of UFC 269. I get that. Not only are both men firmly on the good guys side of the equation — Poirier has his foundation and Oliveira has provided for his community — but both have toiled for years in the MMA trenches before finding their footing and becoming the two best fighters in the current UFC lightweight landscape.
