Most radical style changes in boxing history?

[Silence]

My two favourite fighters have significantly changed their style in Kovalev and Wilder 2.

What are historic examples like that?

Hector Camacho. He turned from an exciting fighter into a slap-and-run boremeister after Edwin Rosario almost knocked him out.

[IronDanHamza]

Ray Leonard in the Duran rematch would be the obvious example.

Mayweather when he fought Zab Judah, the first time he'd been in there with a faster man.

George Foreman came back and changed his style totally.

The best fighters are the one's who can make adjustments.

Like Joshua after Ruiz a$$ whooping.

Not really, though I see what you mean. But Camacho became a genuine Roadrunner after the Rosario fight.

George Foreman came back and changed his style totally.

Do you consider Ali's tactics vs Foreman a change of style as well?

Do you consider Ali's tactics vs Foreman a change of style as well?

I'd say that's more down to Ali's legs being very passed their glory days.

[The D3vil]

Mayweather from "Pretty Boy" to "Money" because of his brittle hands and not having power to carry up to 154.

Foreman in the 1970s vs. the 1990s.

Klitschko changing to a go who just pecks away with a jab and holds when a fighter gets too close

[Willow The Wisp]

Ali rode the aging process like a skilled surfer rides a wave. He was the Beatles of Boxing, ever ready to reinvent.
