I believe all good fighters have learn both of wrestling and striking because you can easily lose with either one technique you're not mastered. If a fighter only learn wrestling striking, he will not able to defend himself when his opponent taking him down. If a fighter only learn about wrestling, you can got KO'ed when you're too close or don't have a sense to predict his next move.
Alex Pereira and Israel Adesanya are the example they have learn wrestling in order to defend and escape from ground fight and they still comfortable to rely on their striking technique.
I believe that most fighters now learning both Striking and Wrestling and it is really essential for fighters to be well-rounded in these sports, and Israel Adesanya is pretty much aware that being a champion needs dedication to his work if you watch his youtube channel you can see that he is practicing wrestling because his striking is fluid now because of his kickboxing days, he is more into training wrestling now, While Pereira is just to training wrestling but he is into it, and going up the division I don't really know if it is a good thing or a bad thing for him, but let's just wait and see,
What I dont like about Nate behaviour, is not that he has used his professional skills against a regular guy (it does not look like he trains something), but the fact that after the guy was out, he releases him and unconscious body felts back. The guy fells back on back of his head on a concrete. If there were a border, the could have died from that hit. Also, if a guy is unconscious and on back, he could swallow his tongue and choke. That is why he should be left on a side. That is one of things I was taught in gym. If the guy is KOed, rotate him on side and never leave on back.
He also attacked the guy with the knee, I don't really know what the guy is saying to Nate Diaz, or why is he approaching him, while there are so many are happening in the back, there are other people fighting, but then Nate Diaz is choking the Logan Paul Look alike, maybe Nate though it was Logan Paul all along, that is why he attacked him,
And here are what I think about a few fights on the UFC Fight Night: Song vs. Simón with Sportsbet odds
Yadong Song(1.99) VS
Ricky Simón(1.83)For this fight, Song Yadong is a decent striker, surely he got power in his punch that could deal Ricky Simon great damage when connected but because Ricky Simon is a wrestler I really think that he can out-takedown Yadong if Song Yadong got decent takedown defense then I guess this will be a hard fight for Ricky Simon, but if Ricky Simon pretty much consistent and don't give up with his takedown a takedown can eventually done against Yadong, you can say that Yadong also have his wrestling game but not as good as Ricky Simon, that is why my pick is Ricky Simon,
Caio Borralho(1.28) VS
Michał Oleksiejczuk(3.75)For this fight Michal Oleksiejczuk, if I pronounce his name I would surely destroy it for sure, but Oleksiejczuk sure has power in his punch that could knock out his opponent with just 1 punch, while Caio Boralho style he would likely want to have some distance between them so he can execute those kicks and he is a well-rounded fight so he can have many ways on taking Michal Oleksiejczuk whether it will be a knee, kick or in the ground,
