Fury's time has come and gone. I was impressed he was able to beat Klitschko, who for some reason looked like he was scared to be in the ring that night, but Fury had some mental health issues and didn't stay in shape. Even though he's not an old man, it is doubtful he'll be able to regain his form. Wilder and Joshua are almost as tall as Fury is but have much more punching power than Fury does and are much sharper right now because they've been active. If Fury fights either one of those guys, he will get KO'd.
