That era with heavyweights being in that 220-240 range was the best. Just a completely different level of athlete and legit baddest man on the planet.
This era has a lot of guys in the 260+ range. Yes we probably get more first round KO's, but I always feel like HW fights are 50/50 now.
31-1 in HW against top opponents (whatever people want to say in hindsight). Does anyone really look at those opponents and think that Stipe, DC, even Jon Jones or Francis make it through that gauntlet undefeated? Then continue fighting for 10 years and go 40-6?
Stipe is 20-4
DC is 22-3
Jones is 26-1 (Closest to Fedor, but has less HW fights than Dan Hooker)
Francis is 17-3
All need 25 fights to even get to the same numbers of matches, let alone continue winning for the next 10 years as the fight all those fights.
No one is going to equal it especially at HW.
