prob the 80s because it had so many superstar ATG's in and around the same division fighting eachother, we seen the emergence of mike tyson at heavy aswell
I only remember snapshots of the 80's due to my age (Tyson here, Leonard there, Hagler, etc.), but going back and actually watching the fights I would say that era. I was really brought up on fights in the 90's though, that's when I was a teen and sparred.
