2019 was a mixed bag for WBO, IBF, IBO, WBA heavyweight champion Anthony Joshua.
In June, he lost his four world titles in a major upset, when Andy Ruiz dropped him four times for a seventh round stoppage at Madison Square Garden in New York City.
Joshua got revenge and reclaimed the belts in their December rematch, when he traveled to Saudi Arabia to win a dominant twelve round unanimous decision over Ruiz.
In the rematch, Joshua was not his usual aggressive self. Instead, against an out of shape Ruiz, Joshua decided to use his legs and the jab, to create as much distance as possible to outbox Ruiz in just about every round.
Whyte believes the most recent version of Joshua is here to stay - based on the historical changes that other big heavyweights have made, like Lennox Lewis and Wladimir Klitschko. Both suffered unexpected knockout defeats, and each boxer revamped their style to avoid the same occurrence in the future.
"We've seen this before - Lennox Lewis was an aggressive fighter on the front foot but got knocked out by Hasim Rahman, then changed his style," Whyte told Sky Sports.
"People forget Wladimir Klitschko was one of the most aggressive heavyweights for a long time, but he got done by Ross Puritty, Corrie Sanders and Lamon Brewster then changed his style. Joshua will be the same.
"Tall heavyweights start their careers very aggressively, but then? Even Deontay Wilder, when he was clocked a couple of times by Luis Ortiz, thought 'I'm just going to wait'. We have seen this time and time again in history, and it's always the same. Let's go further back - [Joshua's fights against] Carlos Takam, Alexander Povetkin, Joseph Parker. There were signs of caginess and not liking getting hit."
