Do you not think Yaroslav Amosov has a reasonable claim of being the best Welterweight over Leon Edwards? I personally don't thunk Amosov is the best in the world but the claim is certainly reasonable. Mighty Mouse the last few years over Figgy/Moreno? If Usman Nurmagomedov wins the Bellator GP it's going to be a reasonable claim in my opinion yes the best LW in the world. List goes on really, if Kerefov beats Askarov convincingly in ACA he has an argument too.
Dunno. I get this is high profile, I think it's more about the sport being valuable and promotions are showing interest in others talent with deeper pockets to actually negotiate again. Fighters will have leverage, we will see more of this.
