Ok you're simply proving my point. Fine let's look at it:
Matt Hughes - GSP*, Carlos Newton?, BJ Penn? Sean Sherk? Frank Trigg? Top 3 is probably: GSP, Newton (x2), BJ Penn.
*23 year old GSP in his 3rd UFC fight, 8th pro fight. Not the same fighter he would become at all.
The issue here is that, 1. I said Hughes has a much more solid and better legacy than Franklin. But 2. Most of his defenses are against bums and LWs, his top 3 wins aren't even good if we put GSP into context and outside of GSP it's basically over LWs and Carlos Newton who was a champion but from a different era much like Nate Quarry for example, was a pretty good win at the time.
Rich Franklin - Evan Tanner (x2), Nate Quarry, Yushin Okami, Travis Lutter coming off a title shot? Wanderlai Silva x2? Washed Chuck Liddell?
Top 3 is probably: Tanner x2, Quarry, Okami. But as you can see the list of names here aren't much worse or are arguably better than Hughes total list, in context. Franklin simply doesn't have the title defenses and reign Hughes did. Hughes lost his title to a fucking LW at one point and has a significant portion of his top wins over LWs such as Sherk and Penn.
If Franklin didn't run into Anderson Silva he could have had a Hughes' esque run. Hence the problem with comparing eras, because it's not purely based on talent and how "good" someone was. Against their peers yes, but the peers aren't created equal.
Was the run of Newton, Sakurai, Newton, Castillo, Sherk (LW), Trigg, then losing to LW BJ Penn really that impessive? In terms of numbers and stats yes it was, among his peers at the time yes it was, but it's tough for me to have confidence in Hughes abilities like I would GSP's or Fedor's or Silva/Jones/Aldo against fighters generations later. It's very plausible to say Hughes would have been destroyed by GSP's generation even if he was in his prime then.
