Sam Langford Benny Leonard Joe Louis Ray Robinson Roberto Duran Ray Leonard (god, that hurts to admit) Lennox Lewis there are other all time great fighters, but these I feel are the most well-rounded, which I am assuming is what is meant by complete.
know you weren't talking to me but top notch. the first fight with marciano confirmed an entire career of durability
i was thinking the same about olivares, i haven't seen much but from what i've read ruben could really box and move to set up his power when he wanted to.
Of course, Sugar Ray Robinson. Sugar Ray Leonard, Ricardo Lopez, Roberto Duran and John Ruiz....haha.
