Briedis may have been on the slide but he was still best in the division at the time, his only loss to Usyk. And Ramirez got absolutely washed by Bivol a weight class down and got a competitive decision against Hart the first time around. Benavidez struggled against Gavril and looks good against smaller opponents or guys who've already been knocked out before. Plus, he's never fought at the weight class, his rightful weight class. Opetaia has been on a streak and has been avoided for a reason.
I have to strongly disagree about the second part. UFC has competition but on this side of the ocean they've acquired the best talent pool and pit the top fighters against each other at or close to their primes. That's the whole reason for a ranking system in the first place. Their interim champs are only stand-ins until the actual champ comes back from a documented injury, as any other reason goes under review and usually leads to stripping, (unless you're Jon Jones).
In the last decade or so alone, boxing has misses than wins in superfights. May-Pac was 5 years too late, Joshua still has never fought Wilder or Fury, none of which are in their prime anymore, Canelo-Benavidez a no-ski, Loma-Garcia never happened, Tank has never fought Teo, Haney, or Shakur, Kovalev never fought Stevenson, etc.
Once Zuffa finds it's footing in the next year or two, we're going to have a boxing renaissance like the UFC did when they had Anderson Silva, George St. Pierre, Jon Jones, Ronda Rousey, etc.
If most everyone fights under one roof, we have much to look forward to.
I agree Briedis was the best at the time. The first fight anyway. I remember watching that fight live and was very impressed with Opetaia. I still am. But you can't crown somebody as the best when there are legit contenders to the throne.
Opetaia has faced VERY underwhelming competition besides Breidis. And he struggled with Cinkara.
David's fight with Gavril was back in 2017 (the first one, that was close) and Benavidez was only 21. His resume is so much better than Opetaia's. It's not even close. You cannot deny that. And please stop with the "rightful weight class" stuff. If you can make the weight, that weight is your rightful weight class.
As for UFC, I stand by my comments, but I'll also concede I don't follow it. I followed it a bit years back when there were more promotional outfits and the champions of rival outfits didn't fight each other.
