I dunno man. To say "he doesn't even have 10 title defenses" is a bit dismissive considering only one person in the history of the sport has 10 title defenses. Plus Fedor only has 3 :redface:.
Jones record is a little light as far as quantity but his quality is arguably the best. Even his two "joke contenders" were top 10 caliber LHWs even tho they came up from MW. Plus he's done it on the biggest stage...consistently.
Ha! Yeah, that title defenses stat for Fedor is always odd to think about. :icon_chee
As for Chael and Vitor though? You simply don't fight 0 LHW opponents for half a decade and then step in against the champion of the division as anything even close to a legitimate contender. And that's just Vitor. Chael had fought just 1 LHW opponent in the preceding 10 years when he attempted to compete with Bones, and even that was fully 7 years prior and he was finished in the 2nd. Vitor and Chael were 4-5 and 3-5 at 205 when they fought Jones. If those guys were considered Top 10 caliber at LHW then that speaks much more to the abysmal weakness of the division our boy was ruling in 2013 than to their own quality/legitimacy as LHW contenders.
Even giving Lyoto the shot was half a joke, him being 1-2 when he challenged Jones, and even that win was over a 48yo mostly-retired Randy who had been miles away from the top level for at least 4 years. Rampage, his lack of wrestling defense well-exposed by then, getting the shot off a mere 2-fight win streak was far short of impressive. Hell, even the champion Jones beat was a shaky 3-2 in his last 5 and off yet another long surgery lay-off.
Thing about Jones's run is that the names are 'great', but most of the fighters attached to them were far short of fitting that description when he fought them. Meanwhile the likes of Aldo and GSP very rarely fought anyone on less than a 3-fight win-streak.
Aldo's resume is impeccable but it's really tough to gauge his competition level as the division is quite young. Also Aldo is lacking in GOAT intangibles. He doesn't bring the entire sport to attention when he fights ala GSP, Anderson, Fedor, and Jones. Beyond the first Mendes fight(which was epic) he doesn't have many classic or legendary moments. I suppose I'm nitpicking. I just think if Aldo lost the next 5 fights he wouldn't be mentioned any longer. GSP, Fedor, and Anderson could lose 20 fights in a row and still be at the table because they are solidified. They could even pop for roids and take viagra and still be there lol.
I think Jones is solidified too. Say he came back and just started losing to everyone. People would still hold "pre-car crash Jones" up as a mythical unbeatable champion.
Aldo really needs to deliver against McGregor.
The relative number of "intangibles" and "classic moments" could be blamed on the relative sexiness of Aldo's division to the others as much as anything actually meaningful. It's just the nature of combat sports that the bigger the dudes whaling on each other the more love they get (unless they have a big gob on them of course). I find it hard to blame the fighters for that inherent "prejudice".
Even so, of the five GOATs only Anderson has a title fight finish (Vitor) more worthy of legend than Aldo's spinning knee KO of Mendes, a finish followed by the most iconic victory celebration in UFC history when he flew out of the cage and into, then onto, the insanely adoring crowd. The classic flying knee KO of Swanson in the title fight eliminator was also more spectacular and dynamic than anything Jones, GSP or Fedor ever pulled off. Aldo's second fight with Mendes was rightfully officially voted Fight of the Year for 2014. To this day his destruction of the legs of (former 5-defense champion) Faber is so legendary it's still the fight people talk about when they talk leg kicks. None of the other Top 5 GOATs has such an indelible association with a technique (except maybe Bones with eyepokes, lol).
Of course you're right about Aldo's status, but that's really just because many casuals don't give a shit about 145lb guys hitting each other while they find MWs or LHWs or HWs smashing each other far more sexy. That's just the nature of combat sports. But us hardcores have always known the talent at 145 was as good and often better P4P than those marquee divisions, not just because far fewer of the best athletes from FW were poached off the top by big money sports than they were from MW, LHW and HW, but because, demographically speaking, since the average man is around 5'9.5" the talent pool of 5'6"-5'8" men is much bigger than the talent pool of, say, 6'1"-6'3" men.
I say this as a 6'1.5", 210lb man by the way. I have no illusions about how "my" guys stack up in MMA vs Aldo-sized guys P4P. :icon_chee
p.s. Sorry for the novel.
TL;DR Aldo is underrated and Jones somewhat overrated by casual fans.
