Povetkin is still top5 at HW and Huck who IMO never was a great CW put him in big trouble.
Glowacki is a great fighter but I don't see him winning a world title again. He looked awful in his last fight against an Ukrainian who took the fight on late notice. Survived a stoppage loss somehow.
Briedis I think already has a KO over Charr and I've seen Usyk at HW against Joyce when someone in this forum posted it. I don't think they can take the power of Joshua or Wilder. But they can make it a fight with anyone else since HW is shallow af.
I see Gassiev doing better than anyone. He is basically Joe Parker with KO power.
