No, those days are long gone.
Not necessarily (I'm whitepilling here), it's just that you guys are expecting there to be a GSP or Jon Jones every generation when that simply isn't the case.
Young, interesting prospects pop up all the time, most of them just fizzle out, is normal. Joshua Van from last night for example is the latest "Hmm, maybe" at 23 years old, already seemingly well rounded, and improving. Another JJ/GSP will pop up, fighting from the age of 17 and ready to contend by 22 one day, it just might take a decade for that special talent to develop out there in the wild, it could be next year with some kid getting some viral KO and being fast tracked.
One issue is that your pool for those young monster champions is almost exclusively the west, as there needs to be infrastructure in place, developed GDP, etc to be able to get noticed that young, get the quality of training and
opposition in order to make it up there, while not racking up unnecessary mileage. Jon Jones was fighting Stephan Bonnar for his 7th fight.
Part of the problem (especially at WW) is the contenders somehow avoid each other so none of them can really stand out. Belal, Colby, Edwards and Burns spent years beating older fighters like Lawler, RDA, Masvidal, Maia, Wonderboy, Nate Diaz, etc. instead of fighting each other. Now we see guys like Buckley beating the first group of fighters I mentioned. They're not beating "killers." They're beating guys who were killers 5 to 10 years ago.
I think it's partially due to fighters wanting to pad resumes with washed "legends" and partially due to matchmaking that goes too far trying to "not kill off too many contenders." Think about LHWs just before and during the early Jones era. Rampage, Forrest, Rashad, Jardine, Machida, Shogun, etc. all fought each other. They weren't looking for 39-year olds who peaked 7 years earlier.
Rank squatting has been a problem at WW for a long, long time, but it seems to be changing albeit slowly. Shavkat vs Garry, Garry vs Prates, Brady vs Edwards.
We still have utter jokes like Kamaru being ranked 5th (in order to give Buckley a "top 5 win") and Covington at 9, but for the most part we seem to have more upward mobility at WW than we have in the last decade. Guys can't rank squat while ducking Brady, Morales, Garry, Prates, Buckley. Now we just have to pray that this generation doesn't end up doing the same thing avoiding eachother, but so far they don't seem like the types.
I miss that LHW era. Compare it to now where we have maybe 6 fighters worth a damn at 205.
