He got his head knocked off by another wrestler who also took him down. The ignorance here is truly fascinating.
This is just a lack of skill in counting. FW Cejudo - wrestler. BW Cejudo, same guy. FTW - Holloway - non-wrestler. Khabib - wrestler. Usman - Wrestler. Whittaker - this isn't well known but Whittaker is actually a wrestler for the Australian National Team as well, so wrestler. Jon Jones - Wrestler. Stipe - Wrestler. We haven't even gotten to the women yet and we already have 6 guys occupyng 7 of 8 possible slots.
Also, I want to note something hilarious in your counting skills. Let's be generous and say that Whittaker "wasn't a wrestler", despite being a national team wrestler. Lets grant that you didn't know that. Lets grant that the 3 female champions are also non-wrestlers, and let's actually count Nunes twice for holding two belts, despite the fact that you only counted Cejudo once for holding two belts. That still leaves you with only 6 non-wrestlers. So not only is the 5 off, the 7 is impossible. So I really have no clue what you're doing running out there with your incorrect stats. Let's keep thinking of ways you could have gotten your number. Maybe you meant "folkstyle" wrestlers. But then you're clearly shifting the goalposts. Fist of all, the quote you are attacking never sets those extra parameters, you're projecting that upon the quote yourself. Secondly, most of those wrestlers do not consider themselves folkstyle wrestlers, since many of them last trained freestyle. However, if you meant "freestyle" wrestlers, you'd only get 3 individuals with 4 titles. No matter what, you just threw an incorrect set of numbers out there and it's not clear what sort of manipulations you did to make the number make sense in your head.
