Promoter Eddie Hearn believes Dillian Whyte had the wrong mindset for last Saturday's fight with WBC heavyweight champion Tyson Fury.
Before a crowd of 94,000 at Wembley Stadium, Fury stopped Whyte in the sixth round with a vicious uppercut.
Hearn, who was not involved in the fight, believes Whyte was too relaxed and cordial in the days leading up to the contest.
Once Whyte arrived for fight week, it seemed to be all smiles and a very relaxed atmosphere between the two boxers.
Traditionally, Fury is as huge trash talker - but that aspect of his game was missing when the two fighters came face to face in the days leading up to their anticipated meeting.
Hearn believes Fury's 'nice guy' persona was intentional to throw Whyte off-guard and place him in a relaxed state of mind.
He feels Anthony Joshua made a similar mistake for last September's fight with Oleksandr Usyk, who outboxed the British star to capture the unified heavyweight crown.
The veteran promoter is not completely sure where Whyte will end up in the future, but he believes the British contender is still capable of winning a world title at some point.
"It was well documented that it was a fantastic payday [for Whyte]. He’s made a lot of money. He could still be involved in some great fights. Can he go on and win a world championship? Maybe when the dust settles and all these belts fragment, he’s a very good heavyweight," Hearn told The DAZN Boxing Show.
"But I just feel that mindset is everything and he had the wrong mindset in that fight, and so did [Anthony Joshua] when he boxed Usyk. You need someone in the ear who can flick the switch at the right time.
"The Dillian Whyte that boxed AJ [in 2015] - that guy was a bad motherf----- - ready to go. Back then if Tyson Fury had tickled him in the press conference in the head-to-head, Dillian would have cleaned him out on sight. It was brilliant mind games from Tyson Fury."
While watching the fight, Hearn felt Fury won every round - and saw Whyte winning one round at best.
Hearn believes inactivity was a factor in the fight. On the other hand, Fury himself has been inactive - seeing action only once in 2020 and once in 2021.
“[Whyte] was getting outboxed, I didn't give him a round in the fight, maybe one round. Again I’m saying this as a fan, and fans will say [Joshua-Usyk], [Joshua] never imposed himself. You have to admire the quality of Oleksandr Usyk and Tyson Fury, they didn’t allow them to impose themselves in the fight," Hearn said.
“I think inactivity played a massive part as well. I think Dillian has fought something like six rounds in two years. It’s very difficult to go in with inactivity and beat a great fighter like Tyson Fury.”
