I mean, no offense, and I know that this is all ultimately subjective, but I don't believe anyone who watched then and now can claim in good faith that the HW talent/performance is at a higher level today. You have Stipe and DC, then a guy in Ngannou who displayed a WMMA-tier skillset in his title fight. You have the ghost of Reem positioned to get another title shot in 2020 when this same guy, without the worry of USADA, was cutting massive weight to not fight at HW in Pride
Yes, Pride's condoning of PEDs obviously plays a role here, but the fact remains that the HWs who built their legacies in Pride were likely fighting vs enhanced opponents. Then there's the fact that Fedor was being routinely WADA tested during his Pride run and Nog's game was always based more on skill than physicality. Not saying they never used but Fedor was automatically at a disadvantage with his routine WADA testing and Nog's game conceivably stood less to benefit from PED use than a more aggressive physical fighter. Regardless it's a moot issue because PEDs were legal and you can only assume the rest of the division were on them in some form
Back to my point, I don't know how anyone can watch the slopfest that is the current UFC HW division and honestly say the talent level is higher than peak Pride. I have to assume anyone who believes this wasn't fortunate enough to have witnessed the Pride era
Here's two random full-fights that I was able to find online, involving 4 Pride HWs ranked anywhere from 2-10 at the time, and tell me with a straight face that you see this level of talent and fight-night performance from the current UFC HW division (keep in mind: 10 min 1st rounds, something that would be laughed at if you proposed it today in a landscape where HWs are lucky to make it past 3 mins while remaining upright)
