Povetkin and Takem have talent. Wilder and Stiverne don't. It is that simple. Stiverne fought the laziest plodding fight I have seen in decades from a HW title fight from a so called champ. He had zero ability to cut off the ring. He just followed Wilder around and wouldn't let his hands go. It was total ****e to be honest
Povetkin vs Takam was a fight between 2 well established boxers. Wilder is still a few steps away from that status, but he's getting there.
They all have talent. Wilder is the most gifted between them all with height, reach, good reflexes and speed. Povetkin is the most proven of all. As of talent, Povetkin looked awful and talentless vs cruiser Marco Huck, who isn't anything special in terms of skills, but almost stopped him in 7th round. Just a bad night for Sasha. All of these four in their top shape would beat Huck
Takam had 2 good performances, old Thompson and Perez, he wasn't much more proven than Wilder is now.
