When you are the champion and you are packing out stadiums you don't have to travel, you can't criticise him for that. I am sure that Fury would have fought Wilder and Klitschko in the UK if given the chance.
Whatever you say about Ruiz, he is a class above some of the boxers Fury has struggled with recently. Unlike Fury Joshua isn't allowed to have an off day....imagine the flack that he would have got if Joshua had taken on and struggled against the likes of Schwarz and Wallin. He would have been hung out to dry even just for taking those fights.
Fury didn’t struggle against Schwarz at all he pummelled him in 3 rounds.
