Probably the top 5, no matter how you want to arrange it. Islam if he ends up beating Arman and then someone like say, Topuria might end up in this discussion. Another belt could help too. Volk is similarly so, if he can beat Lopes and then defends vs Evloev he's right up in the discussion. DDP if he beats Khamzat will start carving out a case, would still have more work to do but it's been a hell of a UFC run however sloppy it may have looked. I dont think anyone else currently has a big shot at getting their name onto the list, maybe if Topuria shocks us and beats an Oliveira/Gaethje and then upsets Islam but his 145lb run was so short lived it felt a little ducksauce..
