Former WBO heavyweight champion Shannon Briggs believes that he would have certainly derailed a potential fight between David Haye and Tony Bellew.
Briggs and Haye were in talks to fight each other back in 2016.
As part of their discussions, Briggs fought on Haye's undercard in May 2016. Both of them scored early knockouts, to set the stage for a potential showdown in the fall.
But the fight never happened.
Haye walked away from their discussions to set up a March 2017 clash with Tony Bellew.
And when Haye was stopped in the eleventh round of that bout, he would eventually set up a 2018 rematch with Bellew - and suffered a crushing fifth round knockout.
After getting knocked out by Bellew in back to back fights, Haye retired from the sport of boxing.
Briggs feels confident that he would have knocked Haye out in 2016 - which in turn would have stopped the Bellew bout.
"It would have been an early night," Briggs told Sky Sports.
"When I'm angry, when I've got something to fight for, I'm charged up. Two guys who don't like each other is a great fight. If David Haye had fought me before he fought the Bellew fight, there wouldn't have been the Bellew fight.
"I ain't the prettiest brother, but he would have been looking like me after the fight. He would have never fought again."
In the opinion of Briggs, Haye will not remain retired and will likely return to the ring at some point.
If Haye does return to the ring, Briggs says he'll be ready to face him.
"That Bellew wasn't enough. He'll still feel like 'I can get one more shot', and I think he's going to come back," Briggs said.
"My gut feeling says David is going to come back, and I'm going to be waiting for him."
