HW: Bader is not a top 5 HW imo. Sure the UFC division is shallow but he als rather small and i see Stipe, DC, Francis, Curtis, Jarzinho, Volkov and Overeem beating him with relative ease.
At LHW: that should def be his better weight class, but depending If Gus comes back and how, i still see Jones, Reyes, Santos, Smith (not sure), Corey and Jan beating him.
MW: Lovato is pretty tough but also rather one dimensional. He could be a top 10 fighter. But most contenters would beat him quite comfortably.
WW: Lima is a tough one, since im very high on him, but WW is pretty deep rn. I think he could def hang with the top 5 but to really tell if he could be champ, is too early rn imo.
LW: Pitbull gets demolished by Khabib and Tony and pretty easily besten by DP and Gaethje. Other than that he could propably bei competitive with a lot of guys even tho he might be undersized for the division.
FW: i dont think he beats Holloway, but Volk might actually be a pretty good matchup for him. FW is a shark tank rn with KZ, Zabit, Yair etc. But i believe he might be able to hang with most of them.
