Both of his knockdowns in the fights he lost in weren't massive punches. He couldn't get up like his son Tyson, looked like he didn't want to either, id say if John got hold of anyone he would do damage, but if he was to get dropped on the cobbles with a decent whack I don't think he would get up, he would show his age. Big John Fury running 5miles a day, hitting the bag and doing some weights doesnt make him a beast of a fighter like he thinks it does, alright hed beat the average man on a street fairly easily, but he wouldn't beat many trained fighters. Fairplay for the confidence but he shouldn't be calling out anyone below 50. He obviously underestimates youth and athleticism in a fight, and thinks he can win on heart, size and nastiness alone,.
