All of the fighters I named competed in the Olympics. The fact that they don't meet your standards is a separate issue.
Of course it matters - context is everything. You used the UFC signing 'Olympic' athletes as an indication that they are getting some of the best there is to offer. If you back peddle like you meant it another way, we have to play a game called 'stupid or liar.'
No, Yoel Romero who was an Olympian 16 years ago and Hector Lombard who was an Olympian 12 years ago are not elite athletes by other professional sports standards. In terms of NFL, NBA, MLB, that is just not the case because competition is too high.
Further, guys that are large enough to compete in other professional sports only enter MMA as a last resort. This is reflected in the poor risk -vs- reward in the current landscape.
There isn't any High School or College MMA. There isn't any MMA in the Olympics, either. So there is no direct correlation between an Olympic career and an MMA career.
Of course there is. It is widely accepted that wrestling is one of the best bases for the sport of MMA. Why is the UFC failing to attract elite wrestlers? Why are we shuffling around 2004 Olympians like Cormier and Romero?
We crown 8 new All-American NCAA heavyweights each year. Where are they? Cain was a decade ago. Brock tried out for the Vikings before entering MMA as a last resort.
Cole Kondrad tried out with the Jets before entering MMA as a last resort.
There are far more NCAA All American heavyweights teaching high school gym for 40k a year then entering MMA. That is a reflection of the risk -vs- reward.
Michael Jordan in his 40s was still successful at the highest level of the NBA. He didn't win anything, of course, due to his team being utter crap, but he was still an All-Star and averaged enough points to put him on par with some current top-tier NBA players.
Only a fool would highlight the single most notable outlier in the history of humans playing sport and apply it as a common example. This is willfully ignorant, or you are a moron.
Dan Kelly competed in 2012 (signed 2 years after), Rousey in 2008 (signed 4 years after), Cejudo in 2008 (signed 6 years after), Serrano in 2008 (signed 6 years after), and Bilyal Makhov in 2012 (signed 3 years after). Considering the Summer Olympics only occurs every four years, I think it's fairly common and understandable that you would be a decade or more outside of your Olympics career.
Dan Kelly took
17th place in Judo in 2012. He's also a subsidy to book in Australia, where they have him fighting. He's fought 1 guy you've heard of in Alvey, who summarily put him to sleep.
Cejudo failed to make the Olympic team in 2012, washed out, and then entered MMA as his backup plan.
Jon Jones is one of many elite athletes that have entered MMA. You only consider him to be an 'elite athlete' because you're a physique fetishist. You're certainly not saying it because Jon has the credentials outside of MMA to back it up
Jones is one of the handful of truly elite athletes that have entered MMA, and he's run roughshod over the sport. I have no idea where 'physique fetishist' comes from, Jon Jones was a JuCo national champion in wrestling. How do you not know that?
He was academically ineligible to go to a division I school, which is why we saw him with a national championship in JuCo out of Iowa Central. He has not one, but two brothers in the NFL.
In other leagues such as the NFL, Jon would fit in to the background like his brothers do. He would be considered good. The talent pool in MMA is so thin, he's literally considered the greatest to ever fight.
Wonderboy Thompson is an elite athlete. Cain Velasquez is an elite athlete. Fabricio Werdum is an elite athlete, specifically a world class BJJ competitor. Alistair Overeem is an elite athlete with world class kickboxing credentials. Khabib Nurmagomedov is an elite athlete. RDA is an elite athlete. Jose Aldo is an elite athlete. Frankie Edgar is an elite athlete. Dominick Cruz is an elite athlete. Mighty Mouse Johnson is an elite athlete. Etc. There are a number of 'elite athletes' in MMA. Quite a few of them defy your stereotypical, Football-centric view of what they're supposed to look like, which is why you overlook them.
Heavyweight is a geriatric division with the oldest average age. We've seen guys with obviously middling athletic talent such as Brendan Schaub make it to and succeed at the highest level despite not being good enough for a cup of coffee with an NFL team.
Mitrione never really played in the NFL, bounced around then was shown the door. He goes on to fight for the biggest show at the highest level.
That is simply not possible in other sports. Thats how low the bar is - we can take Olympians from 12 years ago and football washouts on their second and third athletic careers deep in their 30's and they can hang no problem.
If the risk -vs- reward changed in MMA, we would see more elite athletes.
