Steve Cunningham takes credit for flipping Tyson Fury's boxing pedigree
The former cruiserweight world champion believes that his fight against the Gypsy King forced the British heavyweight to change his approach to boxing.
Steve Cunningham was Fury's first fight in the United States and the ex-Navy officer very nearly derailed the Gypsy King's American invasion after sending him to the deck.
However, like Deontay Wilder, he was unable to nail him to the canvas with Fury overcoming the crisis to stop him in round seven.
Cunningham believes that it was the storm he rained down on Fury that made the Morecambe fighter take his fight preparation more seriously.
"Our fight made him switch gears," Cunningham told Sky Sports.
"It showed the people that he can switch gears, that he had a solid chin, that he can get off the floor after being hit with a hellacious shot, then evolve in the fight to secure a win.
"Amir Khan, I love to watch him for his speed, but he does not have a chin. He goes down then gets up with wobbly feet and has been knocked out numerous times.
"We drilled the overhand right every day"
Cunningham credits the late, great trainer Naazim Richardson with helping him perfect the punch that he used to knock down Fury.
