How do you see Joshua as one dimensional can I ask? He's made one mistake as a pro against Whyte and rode the shot and stopped him, other than that done what's put in front of him?
A man who has won an Olympic gold medal, a world championship silver medal and a couple of ABA titles as an amateur is far from a one dimensional fighter in my opinion, beats every man in the what I would say poor division tomorrow.
He cannot fight on the back foot. He's not great on the inside. He has zero upper body / head movement, he has poor footwork. He is a fighter who works off his jab and has genuine power.
The reason he's done what he's done is he has not fought one world top 25 fighter. His power is too much for bad fighters he will always look sensational against dross.
The number one heavyweight at the moment is Tyson Fury - he beat THE man. Fury would make Joshua look ridiculous at the moment he'd box his head off from the outside. Wladimir would knock Joshua out. Wlad hits at least as hard as Joshua and since he adjusted his game about twelve or so years ago no-one has ever come close to having Wladimir Klitschko in trouble, he is very, very difficult to land on and once Wlad lands the right hand on the static Joshua it's lights out.
That's just two fighters there are others out there that I'd expect to beat Joshua. There are people out there that are SEVERAL levels above anybody Joshua has faced so far.
