Unlike George foreman and Sonny liston, Deontay Wilder lacks many Fundamentals he only has one weapon and his explosiveness that he had is gone it is over for him. The fact he was inactive for so long did him no favors, because he just got worse since his speed deteriorated. Everyone knows how to fight him and he has no Fundamentals, he better stay away from Zhang or Francis he will get killed.
Probably if he got the opportunity, he just needs to make sure he doesn't come in with an injured right hand like he did against Parker.
Maybe a belt like the WBF. I'd like to see him go over to Glory kickboxing and see how he does there. Wilder vs Verhoeven, Osaro, Plazibat or Ben Saddik would be interesting. I've also really wanted to see Wilder vs Hari for some reason. Those these days I wouldn't be surprised to see Hari lose even that one.
