80's and 90's easy. You have the 4 kings in the 80's and then you have probably the greatest HW eras in history possibly second to the 70's.
Went with 80s and 90s bc that encompasses the 4 kings era, the preceding era of welter, 90s middle and heavyweight, Larry Holmes and Mike Tyson, Mike spinks clearing out a deep lhw division, arguably the greatest cruiserweight fight ever, Julio Caesar Chavez, Pryor vs arguello... The list just goes on...
This is the most interesting era ever for heavyweights in terms of the total roster. Guys like Jalolov and Dychko just need to be allowed to fight contenders and champs.
