I will be honest, but I cant see Nate Diaz in Bare Knuckle Fighting Championship or in other bare knuckle organization. Nate is more of a wrestling guy (black belt in BJJ, 11/20 wins are by sub). I havent noticed super elements of boxing in his fights. Strong chin wont help him to win in a bare knuckle fight. His favourite of keeping hands low and fighting relaxed decreases chance of winning in a bare knuckle fight by 2. Maybe BKFC only wants a big name in their roster, but with Nates unserious approach to fights and training will make him be kicked quickly.
He might have the BJJ belt, but I think he likes to brawl more, so in my opinion, he surely will have a spot for the Bare Knuckle Fighting Championship, surely there is no kicking allowed and I think Nate has seen his option of Clinching and punching his way where here the only allowed weapon is your bare hands, pretty much I think Nate will capitalize with the allowed Clinching on his advantage, and I think he surely thinks of a way or a plan before getting on board,
Nate Diaz will do his best to win, but some of his skills will be somewhat limited against Chimaev. There are only local athletes in EagleFC, I wasn't sure if they would receive such a phone call. But as you said, there is money to be made outside of the UFC, and I'm sure Nate Diaz will make a good choice.I can't even imagine how it will turn out if he wins in his last game but leaves the UFC against Khamzat.
For me, it is still a question of how he can handle Khamzat Chimaev, I mean Nate Diaz has one tough chin but against Chimaev that has power, I am sure that Dana White had picked the right guy in assassinating Nate Diaz, but for me, I am favored of Khamzat Chimaev but if Diaz will win this, it will surely go down into history books the name of Nate Diaz to put a losing record on Chimaev, that is why I am still excited on the fight because Chimaev still can not underestimate Diaz because Nate Diaz is still one tough nut to crack,
I heard that fighters are often ending up with broken fists and hands in Bare Knuckle Fighting Championship, so it's not only the face that suffers damage.
That means recovery needs to be much longer and you can't have many fights in one year, that is not something Diaz likes.
Well, the BKFC should analyze it and because there is no protection on their hands they are really prone to breaking their fist and hands, and they should have proper care for their fighters by giving them Xrays and check-ups on their fighter knuckles as a protocol, and fighters should have an iron knuckle in performing in these crazy events, which is I think you can train your knuckles but by obtaining broken bones and eventually healing it will make it stronger, I don't know if this is real but this is depicted in movies and other media
