I'm curious about the actual percentages of where posters lie on this topic. Posters seem to generally accept that size is important, hence weight classes, including among hw's. I'm just wondering how many believe that the continued growth in size of HW's over the ages is a remarkable coincidence, or rather indicative that HW's are getting bigger and better H2H? Make no mistake, Joe Louis and Ali are my top 2 HW's all time, but on the basis of their in-era resume and achievements, not on the basis of H2H. All sports with tangible records have records that last no longer than about 30 years. They all typically also see an increase in size similar to what the HW division has seen. IMO, size is even more important in combat sports than in most of those other sports (hence the existence of weight classes). So I don't see any HW whose prime was more than 30 years ago beating ATG's of the last few years. Tyson is the oldest HW champ I can see having a chance against the K's. The world population keeps growing, globalization means that markets keep opening up new populations to boxing (and other sports), and professionals keep learning new tricks of the trade about what is most effective. High school sports are separated into divisions based on the size of their schools, because they understand that schools with more students have a biggest pool of talent and therefore have an unfair advantage. The concept is the same here. I have my views, I know others have different view, all are welcome, I'd just like a sense of where people stand on this.
