Let's start with Oliveira. I was incredibly impressed with his win on Saturday, as it showed, once again, that despite clearly not being at his best anymore, "Do Bronx" still has plenty of game left. That's incredible for a fighter who is pushing 40 and has already spent 15 years in the UFC. Father Time is catching up to Oliveira, but he's not laying down on letting the old man grab him just yet.

And that, in many respects, is the crux of Oliveira's greatness, his longevity. For many years, Do Bronx was a good fighter and a fun one, but not a great fighter. But he stuck around and kept improving, and eventually, everything fell into place. Suddenly, Oliveira had the counting stats that come with fighting so often for more than a decade, but then he also had real achievement in his lightweight title run. And now, in his final act, he's still putting up great performances, which stands in stark contrast to Penn's end, which functionally removed him from GOAT conversations that he had been a fixture of for a decade, because people remember the long string of terrible losses at the end.
