The 70's. No doubt in my mind whatsoever. Look at the heavyweight scene,in the first half of that decade,in particular. Muhammad Ali,Joe Frazier,Ken Norton and George Foreman were the cream. Just below them were capable guys like Jimmy Young,Jerry Quarry,Ron Lyle and Earnie Shavers. Looming on the horizon we had a young Larry Holmes. In the 90's,only two names figure. Lennox Lewis and Evander Holyfield. Riddick Bowe was talented,but blew out after 1993.
Michael Moorer, Ray Mercer, Tony Tucker all beat Jerry Quarry and maybe Jimmy Young. Lennox on his best day beats any fighter from the 70's.
lewis was the only stand out.quarry would take moorer apart and outbox mercer and tucker.big george would ko all apart from lewis.
The 90's had harder hitters and more depth. I have long contended the 70's as being vastly overrated. Frazier peaked in 71, Ali was on a steady decline the entire decade, Foreman was fed a string of no-hopers until his well timed meeting with undersized, fading Frazier and china-chinned Norton. It was "America's Decade" as the cream of the heavyweight crop were Americans and the US had little hold on boxing's other divisions. By '76, the division is in shambles, and the title was soon plucked like low hanging fruit by a coke fueld cruiserweight with 7 fights.
even with all those flaws it was still better than the 90's.foreman had faded so badly he managed to win his old title back in the...........90's when he was 78
25 HWs in the 90s in no order: Lennox Bowe Holyfield Tyson Tua Ibeaubuchi Vitali Wlad rudduck Mercer Old Larry Holmes Old Foreman Moorer Akiwande Morrison Bruno McCall Maskeev Golota Rahman Corrie Sanders Gary Mason Tucker Hide Shannon Briggs Now granted some of those didnt do there best work in the 90s but neither was Ali and arguably Frazier and Holmes in the 70s. Take out Ali, Holmes, Foreman and Frazier and the rest arent that impressive, especially when you subtract Norton, shavers, Quarry, Lyle, Young. Outside of the top10 its weak compared to the 90s
