This is total nonsense IMO. Come on now. Fury and his familly are mental, they're travellers and into fighting, I doubt they are scared of anyone and that's before we get onto what Tyson Fury actually did boxing wise. He signed up to fight David Haye who was/is a very dangerous, powerful fighter, twice, he got annoyed that it didn't happen and then went and fought Wlladimir Klitchko in Germany and won with ease, with his hands down behind his back at one point. Klitchko had a bruised up face and couldn't get near Fury. Yet now Joshua has knocked out Wlad late on, all of a sudden it was a disinteressed or past it Wlad at the time Fury fought him. Lets not forget that Joshua got put down badly in his home country.
Regardless or what you think of Wlad then and now, there is no way you can accuse Fury of being scared to face challengers, no way at all.
I think its just a case of what we see in everyday peoples lives and in sportsmens lives too, Fury has familly, kids, likes going out and eating bags of crap from Spar or whatever it was. He's the Anderson, Hatton, Gasgcoine of the HW division. I do think also, probably because of how he eats and drinks, is very up and down. One minute he thinks he's capable of anything and loves boxing, the next he hates it and wants to quit. One day he tweets this then he's retiring. He's very Ronnie O'sullivan.
Scared? No chance. As Deonty Wilder recently said, Fury, not Joshua set all this up and freed up things.
