Fought truly different generations of fighters? For example, Kosta Tszyu had a extremely fast start to his career, fighting the remenants of the last generation in the process. La Porte, Bramble, and Roger Mayweather. He'd also face Chavez, but from the next generaiton he went against the likes of Zab Judah and Ricky Hatton, two of the biggest draws around today still. So, who else?
Obviously there is Duran. Holyfield's early start against guys like Qawi and DeLeon and then older heavyweights in Foreman and Holmes, heavyweights of his generation in Bowe, Tyson, and Lewis, and recent heavyweights like Ibragimov. Related to that, both Foreman and Holmes fought elite heavyweights of two generations. Ray Robinson meeting guys like LaMotta, Gavilan, Armstrong, Angott, Bell, Graziano, and then later in his career, Fullmer, Giardello, Archer, etc. I'm not sure if it's true, but I remember hearing that Jersey Joe Walcott fought two generations of the same family, a father and later his son.
Thats true about Walcott im sure, the story is something like he stopped them both in the same round, or beat them on the same date of different years, cant remember, but theres a twist to that one.
The father ans son were Phil Johnson and Johnny Allen, both Ko'ed in Three by Walcott. Joe Choynsky goes drom bare-knuckled guys Glover and McAuliffe up to Jack Johnson while Archie Moore goes from Bivins to Ali.
ali must have taken in 3 generations. you have liston and patterson, through to your fraziers and foremans and then holmes, spinks, berbick .
Azumah Nelson fought Wilfredo Gomez (who fought Carlos Zarate) and Genaro Hernandez (who fought De La Hoya and Mayweather). De La Hoya himself fought Chavez, Camacho and Whitaker, as well as Sturm, Mayweather and Vargas.
Tyson fought Berbick, Spinks, and Holmes. And then you have Gulotta and Lennox Lewis. Isn't wasn't the same Tyson for the latter, but he arguably faced two different generations of fighters.
Jersey Joe Walcott stopped Phil Johnson in 1936 tko 3rds Johnson suffered a broken nose.In 1950 Walcott stopped Harold Johnson,Phil's son in 3 rds Johnson retired with a back injury
