Fighters with multiple trilogies

[ladiesman217]

Pac has 3 trilogies in his career (one being a quadrilogy). Besides him and Morales, does anyone know any fighters who had more than one trilogy in their careers?

EDIT: Forgot that Ali fought Norton 3 times so that makes him one of them.

Ali against Norton and Frazier.

It was more common in the past eras. Nowadays it is very rare.

I believe Evander Holyfield fought John Ruiz and Riddick Bowe three times each..

[The Gambler1981]

Ray Robinson- Fulmer, Bobo Olson, LaMotta, Sammy Agnott, and some others later on in his career.

Ruben Olivares also had trilogies with Chucho Castillo and Bobby Chacon..

Was going to post Robinson.

Thinking of modern fighters, I can't think of many. It's sad that we never get Barrera/Morales/Marquez, could've had trilogies all round.
