People have a very high opinion of the "athleticism" and "aggression" of the average dude. Just watch WSHH fights, Felony Fights, whatever. These are guys who actually look for trouble and usually find it and they are fucking terrible in every conceivable way. No coordination, no speed, no technique, no endurance, no nothing.
Then consider that the vast majority of men have not been in ANY kind of fight since elementary school.
Then consider that the average man cannot even bench press his own weight for one rep.
This notion that the average man is more "athletic" than Ronda is fucking absurd. As sloppy as she looked in her last fight, she looked like Anderson Silva compared to the guys in WSHH etc.
The vast majority of men would not last long enough for even gas to be a factor. I mean, it's another big advantage in her favor, but let's be realistic, they have
1 - zero way of stopping her from clinching (outside of a hail mary lucky punch).
2 - zero way of stopping the takedown
3 - zero way of stopping the armbar.
Yeah, there are some larger, well trained guys that would clean her clock or smaller guys who fight in the UFC who would destroy her
But by far and large she destroys most humans on this planet in a fight
