I like Paddy over all other options, because he was the only one not being a baby about deserving a title shot. However, UFC probably knows Gaethje is on his last legs and milk him before he expires, give Topuria a highlight reel KO, before fights that Topuria probably won't look as good like with Paddy or Arman.
Don't like this fight, but Gaethje has a puncher's chance, maybe more than Olivera. He's smarter with his entries and more defensively sound. Also could give Topuria some issues with calf kicks maybe. Still, UFC is milking the cow one last time. It's not as bad as Colby, but still annoying how consistently the UFC rewards guys who sit around and demand title or nothing.
